Kazeros Act 1 Extreme drops a player straight into a single boss fight with no warm-up gate, so the only question that matters before queuing is whether the character in front of the screen actually clears the bar for the chosen difficulty. This guide lays out the item level gates for Normal, Hard and Nightmare, the engravings and gems worth checking beforehand, the card sets that carry the most weight into Aegir, the consumables a no-revive Nightmare attempt calls for, and how an 8-player roster should be split so nobody wastes a weekly lockout on a run that was never going to close.
Kazeros Act 1 Extreme Item Level Requirements for Normal, Hard and Nightmare
Kazeros Act 1 Extreme puts players back against Aegir, the Oppressor, the same boss from the original 2-gate Kazeros Raid, but rebuilt as a single, standalone encounter that starts fighting the moment the party loads in. Lost Ark's official 2026 roadmap confirms the raid opens the West's first Extreme tier on July 15, 2026, after the Korean version already ran the same content from April 22 to May 20. The entry requirements are set at Item Level 1720 for Normal, 1750 for Hard and 1770 for Nightmare, a noticeably higher bar than the 1660 and 1680 needed for the original story-mode Aegir raid, so clearing the base raid a few months ago is not the same as being Extreme ready today.
All three difficulties share a single weekly clear per roster, which means picking a tier is also deciding which attempt counts for the week, since a Normal clear locks out a Hard or Nightmare attempt on the same roster until reset. Normal and Hard keep the Individual Revival system active, letting each character revive once per attempt at the cost of a Phoenix Plume. Nightmare removes that safety net completely, so a wipe there ends the week's shot outright. Normal pays 20,000 gold, Hard pays 45,000 gold, and Nightmare matches Hard's reward while adding an exclusive legendary title on the first clear. Every difficulty also drops the Coins of Fire and Ice currency, which trades for Relic Combat Engraving Selection Pouches, Rare Hell Key Chests and Metallurgy Selection Chests.
| Difficulty | Item Level Requirement | Revives | Gold Reward |
|---|---|---|---|
| Normal | 1720 | 1 per character (Phoenix Plume) | 20,000 |
| Hard | 1750 | 1 per character (Phoenix Plume) | 45,000 |
| Nightmare | 1770 | None | 45,000 plus exclusive legendary title |
Engravings and Gems to Check Before Aegir Extreme
Engravings unlock in stages tied to item level, reaching the full five-slot layout at 1540, so anyone above the 1720 Normal gate should already have every slot open and the question becomes what fills them rather than how many exist. Both class engravings maxed to level 3 are the baseline, and the third combat slot is where a lot of players make the wrong call in extreme-tier content, since Nightmare's lack of revives raises the cost of a single bad hit. Classes with thinner HP pools often trade a slice of damage for a survivability engraving that reduces incoming damage or grants status immunity during a shield window, a swap that costs raw output but keeps a squishier class alive through the patterns that would otherwise end the attempt on the spot.
Gems matter just as much as engravings once the fight turns into a straight damage race. Tier 4 uses two gem types, Crimson Flame for cooldown reduction and Annihilation for damage, with support classes getting extra utility effects baked into the same gems. A character can equip up to 11 gems at once, and a level 10 gem provides the strongest version of its effect, so the practical check before Aegir Extreme is whether the skills carrying most of the damage rotation are sitting on level 7 or higher gems rather than low-level placeholders left over from an earlier tier.

Card Sets Worth Running Into Kazeros Act 1 Extreme
Two card sets currently cover most of the endgame damage builds heading into Aegir Extreme. Kazeros's Legion Commanders, often shortened to LWC, is the long-standing 30-card legendary set built around dark damage and has been the default target for players chasing every remaining percentage point of output. Acquisition got easier alongside the Extreme rollout, since Wandering Merchants now sell one Legion Commander card directly instead of leaving every copy to raid drops. The newer alternative, Light of Conviction, arrived as a replacement for the older Master of Spears set and blends legendary cards with hero and rare pieces, cutting the collection time considerably for players who are not already deep into a legendary card project. Neither set is mandatory to hit the Normal or Hard item level gates, but both close a real damage gap for anyone pushing toward a clean Nightmare clear rather than just meeting the entry number.
Consumables and Loadout for a No-Revive Nightmare Attempt
Battle item choice changes meaningfully once Nightmare removes revives from the equation. Aegir's fight includes at least one push-immunity mechanic that specifically calls for an Atropine Potion, used right as the boss telegraphs a knockback so the party can keep dealing damage through the window instead of losing positioning. Stagger-focused items such as Whirlwind Grenades remain useful for interrupt checks tied to the boss's shield phases, and Life Potions matter more in Nightmare than in Normal or Hard, since there is no Phoenix Plume fallback if a mechanic is misplayed. Filling every consumable slot before queuing rather than topping up mid-run is worth the extra minute, since Nightmare offers no room to recover from a slot left empty at pull.
Party Composition for an 8-Player Extreme Clear
Kazeros Act 1 Extreme keeps the raid's usual 8-player structure, split into two 4-player parties, each needing its own support running Bard, Paladin or Artist to keep shields, healing and buffs covering that half of the roster independently. Because the encounter is a single continuous fight rather than a gated, multi-phase raid with built-in breathing room, a comp built around sustained, consistent damage tends to hold up better than one leaning entirely on long-cooldown burst windows, since there is no natural lull to line those windows up around. Coordinating identify checks in advance, specifically which characters are actually sitting at the item level, engraving and gem levels described above rather than just above the raw entry number, saves a group from discovering a weak link only after the week's single attempt is already spent.
Final Thoughts
The fastest way to know if a character belongs in a given Kazeros Act 1 Extreme difficulty is to run the item level number first, then check whether the engravings, gems, cards and consumable loadout backing that number match the difficulty chosen rather than the bare minimum to enter it. Normal and Hard forgive a single mistake through their revive system, but Nightmare's one-attempt, no-revive structure turns every gap in preparation into the difference between a legendary title and an empty week. A roster that checks its weakest member against these requirements before queuing, rather than after a wipe, is the one that actually spends its single weekly attempt on a real chance at the clear.
