Patch 12.1 PTR Class Changes: Full Overview of Curse of Ula'tek

Blizzard has posted the first round of class changes for the Patch 12.1 PTR, the public test build for World of Warcraft Midnight's upcoming content update Curse of Ula'tek. The notes cover every class in the game and introduce three systemic changes that apply across the board: a visual and audio indicator for missed interrupts, a 25 percent increase to player health and enemy damage, and a broad rebalancing of DPS cooldown throughput against steady state damage. On top of these systemic shifts, nearly every specialization received individual talent, healing, defensive, or damage adjustments, ranging from full ability redesigns to smaller numeric tuning passes.
Blizzard has stated these are PTR values and may change before Patch 12.1 reaches live servers, so specific percentages and thresholds listed below should be treated as a starting point for testing rather than final tuning. The studio is specifically watching how the cooldown rebalance, Apex Talent redesigns, and Midnight Season 2 class set bonuses play out, and further adjustments are possible depending on PTR feedback.
WoW Patch 12.1 PTR Class Changes Overview
The Patch 12.1 PTR class notes are built around three headline systems rather than isolated spec tuning. The first is a missed interrupt indicator that displays whenever an interrupt ability is used on a target that was not casting. The second is a flat 25 percent increase to player health and enemy damage at max level, paired with adjusted health consumable values. The third is a reduction in the throughput of major DPS cooldowns for several specializations, offset by increased steady state damage outside those cooldown windows.
Beyond these three systems, the patch includes class wide healing and absorb increases for several specs, weapon requirement changes for Demon Hunters, a major Hunter auto shot adjustment, Apex Talent redesigns for Arcane Mage, Devastation Evoker, Guardian Druid, and Marksmanship Hunter, plus smaller Apex Talent updates for specs such as Balance Druid and Elemental Shaman. Multiple classes also received Cooldown Manager tracking support for pets, totems, summoned minions, and selected buffs that previously had no dedicated tracking option.
Missed Interrupt Indicator in Patch 12.1
Every class interrupt ability, including Kick, Pummel, and Counterspell, now displays a missed visual above the target's head if the interrupt is used while the target is not casting a spell. The interrupt also plays a distinct sound effect separate from a successful interrupt. Blizzard's stated goal is to give players and group members a clear, immediate signal when an interrupt has been used without actually stopping a cast, since the previous behavior gave no direct feedback beyond the ability simply going on cooldown. This is intended to help raid and Mythic Plus groups recognize wasted interrupts in real time rather than only noticing the missed cast after the fact through damage taken or a boss ability resolving.
Player Health and Enemy Damage Increased by 25 Percent
Player health and creature damage at max level are both increasing by 25 percent, with health consumable values adjusted to match the new totals. Blizzard has made comparable scale adjustments before, citing similar changes at the start of the Midnight expansion and in early Dragonflight. The stated intent is to make incoming damage less spiky and healing gameplay more satisfying, since tuning enemies around bursty damage windows has historically forced encounters to demand very fast reactions to avoid death, which the developers describe as leading to more stressful and less enjoyable gameplay.
Because enemy damage is rising alongside player health, Blizzard says encounter abilities are being hand tuned individually rather than simply scaled by the same percentage, to keep specific mechanics at their intended difficulty. Several healing and absorption spells for DPS and tank specializations are also being adjusted so their relative impact stays consistent after the health pool increase, rather than effectively shrinking in value compared to the new, larger health totals.
DPS Cooldown Throughput Rebalance Across Specializations
Several specializations are having the throughput of their major DPS cooldowns reduced while their steady state damage, meaning damage output outside of those cooldown windows, is increased to compensate. Blizzard's reasoning is that when cooldown damage vastly outweighs damage dealt outside cooldowns, combat pacing outside those windows can feel slow and disconnected from a player's overall performance. The studio says its priority is keeping cooldowns feeling impactful and exciting while making sure damage dealt without them remains meaningful, and that it wants to preserve the gameplay texture that currently distinguishes specs from one another.
Blizzard has explicitly flagged this change as one it will continue observing through PTR testing, with further adjustments or partial rollbacks possible depending on how the rebalance affects specific specializations. This framing applies to specs such as Fire Mage, Windwalker Monk, Devastation Evoker, Elemental Shaman, Retribution Paladin, and several other builds where cooldown windows have historically accounted for a large share of total damage output.
Death Knight Class Changes in Patch 12.1

Blood Death Knight Changes
Blood received a broad self healing buff. Permafrost now grants a shield equal to 50 percent of damage dealt, up from 40 percent, and Voracious now grants 15 percent Leech, up from 12 percent. Relish in Blood healing is increased by 25 percent, Rapid Decomposition now boosts Blood Plague healing by 85 percent instead of 50 percent, Sanguinary Burst now heals for 18 percent of damage dealt instead of 15 percent, and Umbilicus Eternus now absorbs damage equal to six times the damage dealt by Blood Plague, up from five times.
Frost Death Knight Changes
Frost's only listed change in this build is Permafrost's shield value rising from 30 to 35 percent of damage dealt, a smaller version of the Blood adjustment aimed at keeping Frost's defensive layer roughly proportional after the broader health pool increase.
Unholy Death Knight Changes
Unholy received the heaviest rework of the three specs, aimed at reducing how many summoned minions can be active at once. Reanimation has been renamed Lord of the Dead and redesigned so that controlling three Magus of the Dead lets the Death Knight sacrifice them to summon a Lord of the Dead for 15 seconds, which casts chaining Frostbolts between two enemies, with longer remaining Magus duration granting more power. Army of the Dead has been redesigned to summon or empower eight Lesser Ghouls for 30 seconds, during which the Death Knight commands the army through Scourge Strike rather than summoning more ghouls, executing either a Death Order that strikes the current target or an Epidemic Order that deals area damage with reduced effect beyond five targets. Lesser Ghoul damage is up 10 percent overall, while Army of the Dead's Lesser Ghoul damage specifically is down 20 percent, and Necrotic Coil and Graveyard damage are both up 20 percent. Other players can now only see up to three Lesser Ghouls active at a time, reducing visual clutter without changing their effect on the Death Knight's own gameplay.
Demon Hunter Class Changes in Patch 12.1

Demon Hunters can now equip daggers, a change Blizzard says is specifically meant to let the new Devourer specialization use Intelligence based daggers.
Devourer Demon Hunter Changes
Devourer's Mastery: Monster Within has its bonus damage during Void Metamorphosis cut by 66 percent, offset by a 20 percent increase to all ability damage. Void Metamorphosis now increases Void Ray damage by 40 percent instead of 67 percent, Impending Apocalypse's Collapsing Star stacking bonus drops to 20 percent per stack from 30 percent, and Consume damage is up 60 percent, though this does not affect Devour. The net effect Blizzard describes is a spec that hits less hard during its Metamorphosis cooldown but noticeably harder outside of it.
Havoc Demon Hunter Changes
Demon Blades, Blade Dance, and Chaos Strike now require an equipped Warglaive, Axe, Sword, or Fist Weapon. A new talent, Never Say Die, increases damage by 3 percent while above 50 percent health and increases Leech by 5 percent while below 50 percent health, giving Havoc a passive survivability tool. Dash of Chaos has been removed from the talent tree entirely.
Vengeance Demon Hunter Changes
Fracture and Soul Cleave now share the same weapon requirement as Havoc's abilities. Vengeance also received a cluster of self healing increases: Charred Warblades now heals for 5 percent of Fire damage dealt instead of 4 percent, Soul Cleave and Fel Devastation healing are both up 25 percent, Frailty now returns 10 percent of damage dealt as healing instead of 8 percent, Feast of Souls healing is up 25 percent, and Revel in Pain now shields for 6 percent of Fire damage instead of 5 percent.
Druid Class Changes in Patch 12.1

Across all specs, Matted Fur's absorb is increased by 25 percent and Heart of the Wild's empowered Wild Growth healing is increased by 25 percent.
Balance Druid Changes
Blizzard's stated goal for Balance is to slow down Astral Power generation and reduce free spender procs while increasing the damage of each spender, giving players more time to react to Astral Power gains and making pooling resources outside Eclipse more rewarding. A new level 42 passive, Stellar Protection, applies Stellar Flare and generates 12 Astral Power if Moonfire or Sunfire is dispelled. Umbral Intensity now permanently boosts Wrath and Starfire damage by 10 percent rather than only during Eclipse. Starsurge and Starfall damage are both up 10 percent, and overall damage dealt is up 4 percent. Rejuvenation, Wild Growth, and Regrowth healing are each up 25 percent. A new counter aura tracks progress toward Orbit Breaker's Full Moon proc directly in the Cooldown Manager.
The Balance changes are not only direct buffs. Orbit Breaker's effectiveness is reduced to 50 percent from 60 percent, Touch the Cosmos has lower trigger chances from Wrath and Starfire, and several talent positions are being adjusted. Total Eclipse's trigger chance is increased, Sculpt the Stars and Astral Communion have swapped positions, and Sculpt the Stars now reduces Eclipse cooldown by 3 seconds instead of 2. Under Hero Talents, Elune's Chosen loses some Starfire primary target damage through Lunar Calling, while Keeper of the Grove sees lower Haste values on Cenarius' Might and Potent Enchantments.
Feral Druid Changes
Feral's changes target build diversity. Saber Jaws' damage bonus rises to 60 percent per point from 50 percent, Rip and Tear's bonus rises to 20 percent from 15 percent, and Chomp damage is up 30 percent, while Focused Frenzy's bonus drops to 15 percent from 20 percent and Apex Predator's Craving's base proc chance drops to 4 percent from 5 percent. Rejuvenation, Wild Growth, and Regrowth healing are each up 25 percent, matching the increases applied to Balance.
Restoration Druid Changes
Restoration is receiving several usability focused reworks. Innervate no longer makes spells free for 8 seconds and instead restores 25 percent of the target's maximum mana over 8 seconds. Abundance now grants 50 percent increased critical strike chance and 50 percent reduced mana cost on Regrowth while five or more Rejuvenations are active, replacing its previous design. Tranquility now grows roots that absorb damage equal to 60 percent of the Druid's health and prevent knockbacks while channeled, and Incarnation: Tree of Life now casts Regrowth on up to three nearby injured allies on activation. Swiftmend's healing is increased by 40 percent of the heal over time effect it consumes, intended to restore its value as a strong single target burst heal. Overall healing is up 6 percent, Wild Growth healing is up 20 percent with its mana cost up 15 percent, and Lifebloom, Rejuvenation, and Regrowth mana costs are each reduced.
Restoration also receives two new talents. Overgrowth makes Nature's Swiftness cause the next Regrowth to apply Lifebloom, Rejuvenation, and Wild Growth's heal over time effect to an ally, while Flash of Clarity increases Regrowth healing from Omen of Clarity. Several existing talents are also being reshaped: Verdant Infusion no longer extends heal over time effects, Germination no longer increases Rejuvenation's duration, Ysera's Gift now transfers overhealing from the Druid to a nearby ally, and Nature's Splendor has been removed.
Guardian Druid Changes
Gory Fur has been redesigned so Ironfur has a chance to make the next Maul, Raze, or Ravage free, and using one of those abilities has a chance to make the next Ironfur free, creating a two way resource loop. Brambles absorb and After the Wildfire healing are each up 25 percent, Ursoc's Fury now shields for 35 percent of Thrash and Maul damage instead of 30 percent, and Elune's Favored now heals for 18 percent of Arcane damage dealt instead of 15 percent. Lunation's cooldown reduction on Lunar Beam has been substantially increased from 3 seconds per Arcane ability to a flat 20 seconds, addressing what Blizzard describes as awkward rotational pressure from the previous design.
Guardian also has a major Apex Talent redesign planned for Wild Guardian, although Blizzard notes that this version is not yet implemented on the PTR. The new design makes Rage spending capable of awakening Guardian Spirits that attack nearby enemies and generate Rage through Thrash or Mangle, while later ranks add Nature damage to Mangle and Maul, increase Mastery, reset Thrash and Mangle when a spirit awakens, and grant Wild Guardian charges after Berserk or Incarnation: Guardian of Ursoc.
Evoker Class Changes in Patch 12.1

Augmentation and Devastation both receive 25 percent healing increases to Living Flame, Verdant Embrace, and Emerald Blossom, keeping their off healing closer to the new larger health pools.
Augmentation Evoker Changes
Blizzard says the additional crowd control created by Duplicate cast Upheavals was disrupting dungeon gameplay more than intended. The Duplicate Apex Talent has been updated so Upheaval casts from Duplicate no longer knock enemies into the air, removing that unpredictable interruption while keeping the ability's damage and resource generation intact. For Chronowarden Augmentation, Double-time has been updated so the extra stats from an Ebon Might critical strike last 15 seconds, modified by Mastery: Timewalker, while its Prescience functionality is unchanged.
Devastation Evoker Changes
Devastation's Rank 3 Apex Talent, Rising Fury, has been redesigned so that when Dragonrage ends, its effect persists for 4 seconds per stack and Dragonrage itself transforms into a new spell called Unbound Flame, castable up to four times before Dragonrage's cooldown finishes. Unbound Flame deals Fire damage to the target and nearby enemies with reduced effect beyond five targets and generates an Essence Burst on cast. Tyranny has been updated to interact with Unbound Flame so it always benefits from Mastery: Giantkiller regardless of target health, and Risen Fury has been removed as a separate buff now that its function is folded into the new system.
Preservation Evoker Changes
Merithra's Blessing now increases all of Dream Breath's healing by 60 percent instead of boosting only its instant portion by 250 percent, intended to differentiate it from on demand burst heals like Verdant Embrace. Dream Breath's instant healing is reduced by 50 percent while its periodic healing is increased by 118 percent, shifting the spell back toward a heal over time identity. Font of Magic now also reduces the empower time of Dream Breath and Fire Breath by 20 percent, and Temporal Barrier's absorption is increased by 30 percent.
Hunter Class Changes in Patch 12.1

Ranged auto shot damage is increased by 600 percent across all specs, a large baseline adjustment that should significantly increase the contribution of Hunter auto attacks, though the final share of total damage will depend on PTR tuning. Hunter's Mark can now be applied to up to five targets instead of one, which Blizzard says is meant to let a single Hunter reliably mark multiple bosses in encounters with several enemies, without requiring a second Hunter in the group.
The Hunter Hero Talent changes also matter for the final damage profile. Dark Ranger's Bleak Arrows damage is increased by 300 percent, while Withering Fire's Black Arrow damage is reduced by 40 percent. Marksmanship's Dark Ranger nodes also received several follow up changes, including a redesigned Through the Eyes, reduced Black Arrow direct damage, and new Cooldown Manager tracking for Dark Minion summons.
Beast Mastery Hunter Changes
Blizzard says Beast Mastery felt weak outside of Bestial Wrath windows, so Kill Command, Cobra Shot, and Barbed Shot are all receiving steady state damage increases of around 20 to 25 percent. Heart of the Pack has been renamed Razor Sharp and redesigned to increase pet Bite, Claw, and Smack damage by 100 percent. Beast Cleave's duration is extended to 10 seconds from 8 seconds, intended to let players maintain consistent area damage uptime when using Wild Thrash. Wild Instincts has been removed from the talent tree.
Beast Mastery also received supporting talent changes that are easy to miss: Piercing Fangs now increases Kill Command critical damage, Bloody Frenzy's Barbed Shot periodic rate bonus is reduced, and Kill Cleave now only cleaves 20 percent of Kill Command damage during Beast Cleave instead of 40 percent.
Marksmanship Hunter Changes
Explosive Shot has been substantially redesigned to deal Fire damage in pulses over 3 seconds within 8 yards, with a new talent, Unstable Trigger, allowing it to be recast within 3 seconds to incorporate remaining damage from the previous cast. The Headshot talent has been removed, and Deathblow has been reworked so Aimed Shot has a chance to grant the Deathblow effect on the next Aimed Shot, intended to make it clearer when a Kill Shot or Black Arrow follow up is correct. Aimed Shot, Rapid Fire, Arcane Shot, Multi-Shot, and Kill Shot damage are all increased by 20 percent, while Double Tap has also been removed.
Marksmanship also received a deeper Apex Talent and talent tree pass. Take Aim Rank 2 has been redesigned to grant critical strike damage and general ranged ability damage rather than leaning so heavily into Aimed Shot critical modifiers, while Take Aim Rank 3 now lets Spotter's Mark increase both Aimed Shot and Rapid Fire damage instead of only Aimed Shot. Eagle's Accuracy is now a one point talent that increases Aimed Shot damage by 5 percent and Rapid Fire damage by 10 percent. Focused Aim's Aimed Shot cooldown reduction is also lower, Aimed Shot has a new icon, several talents were moved to make Explosive Shot easier to reach, and the Tenacious/Cunning node is no longer required pathing toward Trueshot.
Survival Hunter Changes
A new talent, Razor Edge, grants Raptor Strike, Raptor Swipe, and Kill Command 10 percent increased critical strike chance and 10 percent increased critical damage. Primal Surge has been relocated to an earlier, easier to reach point in the talent tree to encourage more build variety, while Shower of Blood has been removed entirely.
Under the Sentinel Hero Talent tree, Lethal Barbs has been changed so auto attacks have a very high chance to generate 3 Focus rather than granting 1 Focus per auto attack, a change Blizzard says is meant to normalize Focus gain instead of favoring the fastest dual wield setups.
Mage Class Changes in Patch 12.1

Blizzard is adjusting Mage defensives broadly, aiming to improve overall survivability while slightly reducing the power of Glacial Bulwark. A new talent, Improved Warding, reduces area of effect damage taken by 4 percent, Improved Prismatic Barrier now grants an extra charge of Prismatic Barrier on top of its existing bonuses, and Temporal Realignment now immediately heals 20 percent of the Mage's health plus an additional 30 percent over 6 seconds.
Mage Hero Talents also received notable Sunfury updates. Rondurmancy has been redesigned around improving the three Spellfire Spheres rather than increasing the number of orbs to five, Ashes of Inspiration now grants Mana Cascade stacks when the Phoenix casts spells, and Mana Cascade no longer has a stack cap. Memory of Al'ar has also been updated so Combustion and Arcane Surge no longer double the number of Mana Cascade stacks gained.
Arcane Mage Changes
Arcane's Apex Talent has been replaced with a new spell, Prismatic Bolt, which Arcane Barrage has a small chance to trigger per Arcane Salvo stack consumed, dealing Arcane damage to the primary target and reduced damage to nearby enemies while generating four Arcane Charges. Higher ranks grant Clearcasting and bonus Arcane Missiles damage on Prismatic Bolt, plus additional trigger chance and Arcane Barrage damage. Arcane Pulse has also been redesigned with a shorter cast time, a larger 8 yard radius up from 2 yards, a flat 15 second cooldown, and Arcane Charge generation per enemy struck, removing its previous scaling with existing Arcane Charges. Touch of the Archmage has been removed from the spec.
Fire Mage Changes
Blizzard's goal for Fire is to shift value from Combustion burst windows toward steady state damage. Pyroblast and Flamestrike damage are both increased by 15 percent, while the Fired Up Apex Talent's Combustion related bonuses have been reduced at multiple ranks, lowering how much additional damage stacks during a Combustion window relative to the new steady state buffs.
Frost Mage Changes
Glacial Bulwark no longer grants an extra charge of Ice Barrier, and the Hand of Frost Apex Talent's spell damage bonus has been cut roughly in half at each rank. Blizzard says Hand of Frost was providing more burst than intended when combined with Frost's current Hero Talents. Overall damage dealt is increased by 4 percent to offset part of the reduction.
Monk Class Changes in Patch 12.1

Across all specs, Chi Transfer now causes Touch of Death to heal for 60 percent of the damage it deals instead of 50 percent, and Vigorous Expulsion now increases Expel Harm's healing by 6 percent instead of 5 percent.
Brewmaster Monk Changes
Staggering Strikes' Stagger reduction is increased by 25 percent, and Spirit of the Ox's chance to generate a healing sphere is up 20 percent. Celestial Brew, Celestial Infusion, and Awakening Spirit's absorb values are each up 25 percent, and Vital Flame now heals for 50 percent of Fire or Nature damage dealt instead of 40 percent. Fuel on the Fire, Hot Potato, Scorched, Crackling Jade Lightning, and August Blessing are now all trackable directly in the Cooldown Manager.
Mistweaver Monk Changes
Blizzard wants Mastery to become a more competitive secondary stat for Mistweaver and is shifting throughput away from Spinning Crane Kick toward Ancient Teachings. A new talent, Vital Expenditure, increases Soothing Mist's healing by 300 percent at the cost of a 200 percent higher mana cost, set as a choice node against Dancing Mists. Mastery: Gust of Mist healing is up 50 percent, Spinning Crane Kick damage is down 15 percent, and overall healing is reduced by 3 percent to keep the net change balanced. Way of the Crane's damage transfer rate drops to 280 percent from 340 percent, while Jadefire Teachings' bonus to Ancient Teachings rises to 320 percent from 270 percent.
Windwalker Monk Changes
Blizzard is reducing the gap between Windwalker's steady state damage and its burst ceiling. Melee auto attack damage is up 30 percent, Blackout Kick is up 50 percent, Tiger Palm is up a substantial 200 percent, and Dual Threat is up 30 percent, while Zenith Stomp damage is cut by 30 percent and Tigereye Brew's critical strike damage bonus is halved at each rank. Vivify healing is increased by 25 percent. Under the Conduit of the Celestials Hero Talent tree, Celestial Conduit damage is reduced by 25 percent while Temple Training's bonus to Fists of Fury and Spinning Crane Kick rises to 30 percent from 10 percent.
Paladin Class Changes in Patch 12.1

Across the class, Golden Path, Lightforged Blessing, and Brought to Light healing are each increased by 25 percent, and under the Lightsmith Hero Talent tree, Rite of Adjuration healing is also up 25 percent.
Protection Paladin Changes
Blizzard is shifting power out of strong cooldown windows and into baseline throughput for Protection, aiming to reduce threat related pain points outside of those cooldowns. A new talent, Blessed Word, removes Word of Glory's ability to critically strike but scales its healing with critical strike chance and converts 80 percent of its overhealing on the Paladin into an absorb shield. Judgment damage is up 100 percent, Consecration damage is up 100 percent, and Shield of the Righteous damage is up 150 percent, while Hammer of Light and Empyrean Hammer damage are each reduced by 33 percent. Improved Ardent Defender has been redesigned to increase maximum health by 20 percent while active instead of canceling its remaining duration after preventing fatal damage. Sanctified Wrath has been removed from the tree.
Protection's defensive and utility talent layout is also changing beyond raw damage redistribution. Seal of Reprisal has been redesigned so Blessed Hammer reduces enemy damage dealt to the Paladin, Masterwork now causes Holy Armament casts to make the next three Hammer of the Righteous, Blessed Hammer, or Crusader Strike casts bestow Lesser Armaments on nearby allies, and Sentinel has been moved while inheriting Avenging Wrath's critical strike bonus. Avenger's Shield damage is increased by 30 percent, Divine Exaction's Divine Toll effectiveness is reduced, Bulwark of Order's absorb is increased, and Solace now converts a larger share of Consecration damage into self healing.
Retribution Paladin Changes
Alongside the broader cooldown smoothing pass, Blizzard is reducing how much Retribution's rotation depends on consuming Art of War and Righteous Cause procs, and removing interactions with the Skyfury buff that the studio says were overly central to the spec's Holy Power economy. Art of War's bonus to Blade of Justice is reduced to 80 percent from 150 percent, offset by a 40 percent direct increase to Blade of Justice damage. Final Verdict, Divine Storm, Templar Strike, Templar Slash, Judgment, and Hammer of Wrath damage are all increased, mostly in the 15 to 50 percent range, while Avenging Wrath's damage and critical strike bonus is reduced to 15 percent from 20 percent. Under the Templar Hero Talent tree, Hammer of Light's cost is reduced to 3 Holy Power from 5, alongside a 30 percent damage reduction that does not apply in PvP.
Priest Class Changes in Patch 12.1

Discipline Priest Changes
Blizzard says Discipline relied too heavily on Shadow Mend and Void Shield procs for effective healing. Shadow Mend has been redesigned as a passive upgrade to Flash Heal rather than a random proc, and a new talent, Grim Deliverance, increases Shadow Mend's healing by 30 percent and extends Atonement by an additional 4 seconds at the cost of a slower cast time. The Master the Darkness Apex Talent now lets Mind Blast upgrade the next Power Word: Shield into a Void Shield, giving a deterministic path to the effect instead of a proc. Smite damage is increased by 40 percent to make it a more meaningful damage source, and Penance no longer applies Atonement when cast on an ally, a change Blizzard says removes friction between healing allies, applying Atonement, and damaging enemies with the same spell.
Discipline also receives several supporting throughput and Hero Talent changes. Flash Heal healing is increased by 25 percent, Inescapable Torment damage is reduced by 30 percent, and Greater Smite is now a one point talent. Under Oracle, Unfolding Vision has been redesigned so Power Word: Shield or Void Shield can jump to a nearby injured ally if it expires with absorption remaining. Under Voidweaver, Void Blast and Voidwraith damage are increased, and Void Infusion now gives more Atonement healing from Void Blast and Penance while Entropic Rift is active.
Holy Priest Changes
Under the Archon Hero Talent tree, Resonant Energy has been adjusted so creating a Halo increases healing done by 2 percent for 10 seconds, stacking up to four times. Divine Hymn has also been updated to additionally grant Guardian Spirit while channeled, extending an already active Guardian Spirit by 5 seconds, with that bonus duration removed again if the Divine Hymn channel is cut short.
Shadow Priest Changes
Blizzard is aiming to improve Voidform gameplay and reduce Shadow's reliance on Psychic Link for multi target damage. A new talent, Shadeburst, causes Shadowy Apparitions homing in on the primary target to explode for area damage with reduced effect beyond five targets. Improved Voidform now grants an additional 5 percent spell damage and two extra uses of Void Volley, and Voidform itself now grants three uses of Void Volley directly instead of putting the ability on a cooldown during Voidform. Ancient Madness has been redesigned so Shadow Word: Madness increases Haste during Voidform by 2 percent per stack, up to five stacks, with the Haste lingering and decaying over 10 seconds after Voidform ends. Power Word: Shield absorption is up 25 percent, and Phantom Menace has been removed.
Rogue Class Changes in Patch 12.1

Thistle Tea is now a choice talent, letting players pick between its existing automatic activation at low Energy or a new version that must be cast manually. Atrophic Poison's damage reduction effect is increased to 4 percent from 3 percent, and its duration outside PvP is extended to 60 seconds from 10 seconds. Rogue Hero Talents are also touched through Fatebound, with Deal Fate now having a 60 percent chance to grant an extra combo point when Seal Fate triggers, down from 100 percent.
Assassination Rogue Changes
Blizzard is reworking Assassination's Energy economy and addressing what it calls unintuitive optimal play around the Implacable Apex Talent. A new talent, Unstable Toxin, increases Envenom damage by 18 percent while reducing its duration by 2 seconds. The Implacable Apex Talent now increases Envenom damage by 10 percent and restores 2 Energy per combo point spent on Envenom, intended to make refreshing the buff later consistently correct rather than punishing. Deathmark's bonus to Rupture, Garrote, and Lethal Poison damage drops to 75 percent from 100 percent, while Shrouded Suffocation and Avulsion both receive increased bonuses to Garrote and Rupture damage respectively. Blindside's proc chance is reduced at both its base and low health thresholds.
Assassination also receives a 3 percent overall damage increase, while Kingsbane damage is reduced by 15 percent. Internal Bleeding, Iron Wire, Dashing Scoundrel, Motivated Murderer, Rapid Injection, and Venomous Wounds all receive supporting changes aimed at reshaping Energy flow and talent options, while Deadly Momentum has been removed.
Outlaw Rogue Changes
Killing Spree damage is increased by 60 percent, with Blizzard stating the ability previously underperformed compared to simply using other abilities during its channel. Heavy Hitter's bonus to combo point generating attacks rises to 15 or 30 percent from 10 or 20 percent depending on rank, and Hidden Opportunity's chance for Ambush to grant Opportunity is increased to 100 percent of Sinister Strike's chance, up from 80 percent. Zero In's value per stack is reduced to 2 percent from 3 percent, alongside a new interaction that gives it a 30 percent chance not to proc when triggered by a fast 1.8 speed weapon, intended to equalize its value between daggers and other one handed weapons.
Outlaw also gets changes to Between the Eyes support talents: Improved Between the Eyes now causes critical strikes to deal 2.5 times normal damage instead of 3 times, while Fast Action now reduces Between the Eyes' cooldown by 8 seconds and increases the damage bonus from each Between the Eyes stack.
Subtlety Rogue Changes
Relentless Strikes now generates 4 Energy per combo point spent on finishing moves instead of 5, and Shadowcraft no longer stores an extra combo point, instead increasing its auto attack proc frequency bonus to 75 percent from 40 percent. Blizzard says these changes target Energy and combo point overflow during cooldown windows. Lingering Shadow's effect now also applies to Shuriken Storm, and the Ancient Arts Apex Talent now factors in Secret Technique's total damage when creating its shadow clone instead of only the initial hit.
Shaman Class Changes in Patch 12.1

Ascendance has received new icons for all three specializations, a cosmetic update with no gameplay effect.
Elemental Shaman Changes
Blizzard says Elemental's burst during Ascendance windows became too high once Elemental Overload bonuses from both Ascendance and Apex Talents stacked together, so damage is being redistributed into baseline spells for more consistent output. Power of the Maelstrom has been redesigned so Lightning Bolt and Chain Lightning have a 15 percent chance to boost the next Lava Burst's damage by 20 percent, stacking up to twice. Lava Burst and Lightning Bolt damage are each up 30 percent outside PvP, Chain Lightning and Flame Shock are each up 60 percent, while Tempest's direct damage is reduced by 20 percent. Ascendance now increases Elemental Overload damage by 30 percent instead of 75 percent, and bonus Lava Bursts triggered by activating Ascendance are reduced to 50 percent of their normal value. Under the Farseer Hero Talent tree, Chain Lightning now hits up to five targets instead of three.
Elemental also receives a redesigned Stormkeeper: the next two Lightning Bolts become instant and deal 150 percent increased damage, or the next two Chain Lightnings become instant and trigger Elemental Overload on all targets hit. The Feedback Loop Apex Talent is also reduced on Elemental Overload damage and critical damage bonuses, while Rank 1 now adds general Elemental damage. Elemental Blast casts from Fusion of the Elements now grant only 40 percent of the normal duration of Elemental Blast stat buffs.
Enhancement Shaman Changes
Enhancement's listed changes in this build are limited to healing spells shared across all three specs, with Healing Surge, Earth Shield, and Healing Stream Totem each receiving a 25 percent healing increase.
Restoration Shaman Changes
Healing Rain has been reworked to use a 12 second cooldown with an 18 second duration, and recasting it while one is already active will despawn the previous instance rather than stacking. Blizzard says this is meant to give players more flexibility to reposition Healing Rain when needed. This cooldown change does not affect the Surging Totem version of Healing Rain available through the Totemic Hero Talent tree.
Warlock Class Changes in Patch 12.1
Summon Demonic Gateway is now classified as a Utility spell by default in the Cooldown Manager rather than appearing alongside core rotational cooldowns. Under the Hellcaller Hero Talent tree, Blackened Soul has been redesigned so that if the target carries Wither, Chaos Bolt and Shadowburn add a stack to it, with each stack gain having a chance to collapse and consume a stack every second to deal Shadowflame damage until one stack remains. Mark of Peroth'arn now increases Wither's critical strike damage to 215 percent and Blackened Soul's to 225 percent, both up from the standard 200 percent. For Destruction, Conflagration of Chaos has been redesigned so Conflagrate and Shadowburn always critically strike, with their damage scaling directly off critical strike chance, and the talent has been removed from the Cooldown Manager since its effect is now passive rather than a tracked proc.
Warrior Class Changes in Patch 12.1

Rend has been reworked at the class level. Blizzard says its previous implementation across specs was not working as intended, so Rend is now exclusive to Arms, returning to a single target ability with its Rage cost reduced to 10, while Cleave applies it to all targets if the Warrior knows Rend. Fury instead gains a new talent, Storm of Blood, that makes Whirlwind apply Rend to all targets, and Protection gains a new talent, Blood and Thunder, that makes Thunder Clap apply Rend to all targets. Thunder Clap no longer applies Rend automatically just from being known.
Mountain Thane also receives a targeted adjustment because Thunder Clap's higher Midnight baseline damage made Thunder Blast feel less valuable. Thunder Blast damage is increased by 40 percent, while Crashing Thunder's Thunder Clap damage bonus is reduced to 10 percent from 30 percent.
Arms Warrior Changes
Ravager has been redesigned so it no longer boosts Cleave and Whirlwind damage while active, instead causing all enemies it damages to take 25 percent increased Bleed damage for 12 seconds, alongside a 50 percent increase to Ravager's own damage and the removal of its Haste based duration reduction. Bloodletting now grants a 5 percent increased critical strike chance against Rend afflicted targets and causes Mortal Strike to apply Rend below 35 percent target health if known, while Deep Wounds duration is extended by 33 percent. Broad Strokes now grants 6 stacks of Sweeping Strikes whenever Colossus Smash is used. Under the Colossus Hero Talent tree, Demolish's cooldown is reduced to a flat 30 seconds from a variable 45 seconds, and Tide of Battle now boosts Execute damage in addition to Overpower.
Fury Warrior Changes
Whirlwind now innately generates 3 Rage, with Improved Whirlwind redesigned to instead add 1 Rage per target hit up to 8 total, on top of the new baseline. A new talent, Carving Blades, increases Whirlwind's damage by 50 percent when it strikes only a single target, set as a choice node against Meat Cleaver to support single target Whirlwind usage. Rampaging Ruin has been redesigned so that while Improved Whirlwind is active, Rampage's final strike deals area damage to all enemies within 8 yards of the primary target, with reduced effect beyond five targets. Hack and Slash now gives Rampage a 75 percent chance to refund a Raging Blow charge and boost its next use by 20 percent damage, intended to keep Fury's rotation less predictable than the previous, more consistent reset rate.
Protection Warrior Changes
Devastating Focus now boosts Execute damage in addition to Revenge, and Bloodborne now increases all Bleed damage rather than only Rend and Deep Wounds. Fueled by Violence now heals for 125 percent of Bleed damage dealt, up from 110 percent, and Ignore Pain's absorb amount is increased by 25 percent, with Brutal Vitality converting 10 percent of damage dealt into Ignore Pain instead of 8 percent. Ravager receives the same redesign as the Arms version, trading its Revenge and Thunder Clap damage boost for a 25 percent increased Bleed damage debuff on enemies it hits, with a shortened 4 second duration when combined with Whirling Blade. Under the Colossus Hero Talent tree, Demolish's cooldown is similarly reduced to a flat 30 seconds, and Tide of Battle now boosts Execute damage alongside Revenge.
Midnight Season 2 Class Sets Also Affect Class Balance
Blizzard also published the first Midnight Season 2 class set bonuses alongside the Patch 12.1 PTR class notes, and these bonuses should be treated as a major part of the class balance picture rather than a separate cosmetic layer. The stated design goal for Season 2 sets is to make bonuses more complex than Season 1, add more impactful gameplay hooks, use the Cooldown Manager where appropriate, and increase damage consistency without immediately reintroducing the same burst spikes that the broader 12.1 tuning pass is trying to reduce.
This matters because several specs may play differently once their 2 piece and 4 piece bonuses are active. Some bonuses directly extend cooldown windows, improve core rotational buttons, add extra damage events, or interact with new mechanics introduced by the PTR class changes. Because both class tuning and class sets are still in PTR testing, the final Season 2 meta will depend on how these two layers are tuned together.
PvP Movement Slow Tuning in Patch 12.1
Patch 12.1 also includes a broad PvP specific pass on movement slows. Blizzard says the goal is to reduce the power of high uptime snares that are applied automatically during normal rotations, giving opponents more room to use positioning and escape tools. In general, the studio is reducing slows by one tier: 70 percent slows often become 50 percent, 50 percent slows become 30 percent, and smaller slows are reduced accordingly.
This affects a long list of class tools, including Chains of Ice, Typhoon, Ursol's Vortex, Tar Trap, Concussive Shot, Blast Wave, Crippling Poison, Earthbind Totem, Curse of Exhaustion, Piercing Howl, and many pet or Hero Talent slows. These PvP only changes do not replace the PvE class tuning above, but they are still important for arena and battleground players because they directly change how much control many specs can maintain during normal combat.
Final Thoughts
The first Patch 12.1 PTR build sets out a clear class direction for Curse of Ula'tek: give players direct feedback on missed interrupts, reduce one-shot pressure through the 25 percent health and enemy damage increase, and smooth damage profiles by pulling power out of oversized burst windows and pushing more value into steady state gameplay. Underneath those system wide goals, Blizzard is also targeting specific specialization problems, including Unholy Death Knight's summon density, Guardian Druid's Wild Guardian Apex Talent, Marksmanship Hunter's Explosive Shot and Take Aim structure, Discipline Priest's reliance on healing procs, Elemental Shaman's overloaded Ascendance burst, and Retribution Paladin's Skyfury interactions.
The larger balance picture is not limited to class notes alone. Midnight Season 2 class sets are being tested at the same time and are designed to add more gameplay complexity without undoing the burst reduction pass, while PvP receives a broad movement slow reduction pass that will affect how many specs control targets in arenas and battlegrounds. Because Blizzard has already flagged the cooldown rebalance, Apex Talent redesigns, and class set bonuses as PTR tested systems, players should expect additional tuning before Patch 12.1 reaches live servers.
