AION 2 Daeva Bio-Research Base is one of the most useful places to farm Enhance Stones, but its reward system makes every second count. You have just 90 seconds to kill test subjects, collect points and reach the highest reward tier you can manage. The difference between an average run and a strong one is not simply better gear. Choosing the right temporary buff, recognizing elite spawns and moving efficiently between enemy groups can add thousands of points to your final score.
There is another reason to learn the encounter properly: the standard entry allowance is limited and shared with another Daily Dungeon. A disappointing run still consumes an attempt, so repeatedly entering without a plan can cost a substantial number of Enhance Stones over the week. This guide covers the current Global rules, all available temporary effects, elite-targeting strategy, the complete reward thresholds and the best way to use Instant Clear Tickets once you have established a reliable score.
Short answer: Enter Daeva Bio-Research Base at level 30, choose a buff that improves your biggest weakness, and spend the 90-second round prioritizing elites marked with yellow triangles. Each elite is worth 1,000 points, while ordinary enemies provide much smaller amounts. Reach 10,000 points to receive the maximum listed reward of 10,000 Enhance Stones per run. Improve your manual score before using Instant Clear Tickets, because the weekly entry allowance is limited.
Daeva Bio-Research Base Unlock, Entry Requirements and Weekly Limits
Daeva Bio-Research Base becomes available through the Daily Dungeon system at level 30. Open the dungeon menu, locate the Daily Dungeon category under Unknown Fissure and select Daeva Bio-Research Base. This is solo content, so there is no tank, healer or party composition to organize. Your result depends on your own damage, movement and ability to handle the arena's hazards while the timer runs.
The word "Daily" can be misleading here. The standard Unknown Fissure allowance currently provides 14 entries per server each week, with its regular replenishment on Wednesday. Characters on the same server share that allowance. An entry is consumed when you enter the dungeon, even if the resulting score is poor. Eligible Unknown Fissure Challenge Tickets can provide additional attempts, but they are separate from the standard weekly replenishment.
| Requirement | Current Global rule | What it means |
|---|---|---|
| Required level | Level 30 | Unlock the Daily Dungeon before planning a farming routine. |
| Party size | 1 player | Prepare a solo setup with both area damage and elite damage. |
| Run duration | 90 seconds | Movement and skill timing directly affect your final reward. |
| Standard weekly entries | 14 per server | Alts on the same server do not provide another independent set of 14 attempts. |
| Weekly replenishment | Wednesday | Use remaining attempts before the server's weekly reset. |
| Entry counter | Unknown Fissure Entry Count | The allowance is shared with Odylium Repository. |
| Main reward | Enhance Stones | The amount depends on the final score threshold. |
Daeva Bio-Research Base does not consume an Odyle Energy Cube for its standard entry. Its restriction is the Unknown Fissure attempt counter. This distinction matters when planning a weekly routine: having Odyle Energy available does not replace an exhausted Daily Dungeon entry allowance.
How the Daeva Bio-Research Base Scoring System Works
The encounter is a timed score challenge rather than a traditional dungeon with a long boss route. Test subjects appear around the arena, and your objective is to defeat enough of them before the 90-second timer expires. Different normal enemies contribute different point values, but the most important scoring rule is straightforward: an elite test subject is worth 1,000 points.
Normal targets contribute approximately 10 to 50 points according to their type and the scoring action recorded in the current client. That makes one elite worth as much as 20 to 100 normal-enemy scoring actions. A player who spends too much time cleaning up scattered ordinary enemies can lose an entire 1,000-point opportunity when an elite appears elsewhere in the arena.
How to Recognize Elite Test Subjects
Elite test subjects have a yellow triangle above their health bars and tend to appear near the outer parts and corners of the arena. Their names include Giant Krao Bioweapon, Giant Drana Bioweapon, Mutated Sura Bioweapon, Modified Krao Guardian and Sura Magic Bioweapon. You do not need to memorize every name before your first run. Train yourself to recognize the yellow marker quickly, then switch targets before spending another damage rotation on low-value enemies.
The correct priority is usually an accessible elite first, tightly grouped normal enemies second and isolated stragglers last. There is one important exception: if your character takes so long to defeat a particular elite that you miss several other valuable opportunities, your main problem is single-target damage. Address that weakness through skills, gear or your temporary buff instead of following the same route and expecting a better result.
Best Temporary Buffs for High-Score Runs
At the beginning of a run, Daeva Bio-Research Base offers three randomly selected temporary effects. You choose one from a pool of twelve. Because the selection changes, there is no permanent best card that every player can guarantee on every attempt. The strongest option depends on whether you are losing time to elite kills, normal-enemy packs, movement or survival.
| Effect | Grade | Effect | When to choose it |
|---|---|---|---|
| Elite Hunter | Special | Elite Test Subjects have 30% less Damage Tolerance. | Excellent when elites survive too long and delay your next target. |
| Slayer | Special | Increases your Attack by 30%. | Strong general offensive choice for both elites and normal groups. |
| Adrenaline | Special | Increases your Combat Speed by 30%. | Useful when faster attacks and skill execution improve your damage rotation. |
| Worm Carnage | Special | Normal Test Subjects have 30% less Damage Tolerance. | Best considered when ordinary packs are your main clearing bottleneck. |
| Footwork | Common | Increases your Move Speed by 20%. | Valuable when crossing the arena costs more time than killing enemies. |
| Fire Moth | Common | Increases Normal Test Subjects' Move Speed by 30%. | Helps enemies gather around you faster, but can increase incoming pressure. |
| Targeting Weakness | Common | Increases your Critical Hit by 300. | Consider it when the offered alternatives do little for your build. |
| Guardian | Common | Increases your Defense by 30%. | Defensive option when damage taken interrupts your attacks. |
| Ignoring the Weak | Common | Reduces damage dealt by Normal Test Subjects by 30%. | Useful when large enemy packs overwhelm an undergeared character. |
| Ignoring the Elite | Common | Reduces damage dealt by Elite Test Subjects by 30%. | Helpful if elite attacks force you to retreat or interrupt your rotation. |
| Poisoned by Mana | Common | Restores 5% of maximum MP when a Test Subject is defeated. | Situational sustain choice for characters struggling with MP. |
| Predator | Common | Restores 5% of maximum HP when a Test Subject is defeated. | Situational survival choice when incoming damage is the limiting factor. |
Which Buff Should You Pick?
Start by identifying what prevented your previous run from reaching the next reward tier. If elites stayed alive through multiple rotations, compare Elite Hunter, Slayer and Adrenaline whenever they appear. Elite Hunter specifically reduces elite Damage Tolerance; that is not the same wording or calculation as a flat 30% increase to all final damage. Slayer improves Attack, while Adrenaline improves Combat Speed. Their relative value depends on your class and current stats.
If normal enemies survive your area attacks, Worm Carnage can create more immediate value than a movement effect. If you kill everything quickly but consistently arrive late at distant elites, Footwork may improve your score more than another damage modifier. Fire Moth is a more specialized option: faster-moving normal subjects can make grouping easier, but it does not speed up elite targets and may be uncomfortable on a fragile character.
Survival effects are not automatically bad. A dead or constantly interrupted character deals no damage. However, choosing Guardian or a recovery effect when you already survive comfortably usually sacrifices an opportunity to increase your score. Evaluate the three cards against your actual bottleneck rather than choosing only by their Special or Common labels.

Best 90-Second Route and Combat Strategy
The most reliable approach is a flexible loop around the central combat area, with immediate detours toward newly spawned elites. Avoid committing to a rigid route that ignores what appears on your screen. The arena rewards quick target recognition more than memorizing a sequence of enemy names.
Before the Timer Starts
Check your available buffs, make sure your main damage skills are ready and decide which ability will clear normal packs and which will burst an elite. If your usual setup relies on multiple single-target attacks, move an efficient area-damage option into a comfortable hotkey position. A movement ability should also be readily available because elite targets can appear away from your current position.
Consider using an appropriate Combat Speed or Move Speed consumable if your character can benefit from it and the item is available. Do not spend more Kina on preparation than the improvement is worth. The goal is to eliminate an actual weakness in your run, not to stack consumables without checking whether they help.
Opening: Clear Groups Without Chasing Stragglers
Begin damaging the normal test subjects that are already grouped within reach. Pulling several nearby enemies through one area attack is more efficient than turning to kill each target separately. Keep moving around the central space so additional subjects can approach your damage area. If one enemy remains outside your immediate path, leave it temporarily rather than spending several seconds chasing a small point reward.
Pay attention to the floating turret hazards. The arena includes projectile attacks, including visible purple orbs, that can damage you while you focus on a pack. Make small adjustments to your position as you attack. Standing still until a projectile forces an emergency dodge creates unnecessary interruptions, especially for builds with longer attack animations.
Mid-Run: Break Away Immediately for Elites
When a yellow-triangle elite appears, check its location and move toward it promptly. Use your strongest suitable single-target burst once you can attack effectively. Avoid wasting a long cooldown on ordinary enemies immediately before an elite appears if that cooldown is the main reason you can defeat the elite quickly. After the elite dies, resume clearing nearby normal subjects while watching for the next valuable target.
Do not assume every elite will appear at a fixed second that works identically on every run. Watch the actual spawns and adapt. If two valuable targets are present, choose the one you can reach and kill with the least total travel and combat time, unless the other is about to become inaccessible. Efficient routing is about earning points per second, not simply running toward the farthest enemy with the largest model.
Final Seconds: Chase the Next Reward Threshold
As the timer approaches zero, glance at your score and identify the next reward threshold. If you are just short of 9,000 points, for example, even a small normal-enemy kill may be worthwhile. If you are several hundred points short but an elite is within reach, the elite is the stronger target. On the other hand, crossing the entire arena for a distant enemy when only a few seconds remain may produce no additional reward at all.
At 10,000 points, you have reached the maximum Enhance Stone tier currently listed in the Global client. Any additional combat score does not increase that listed payout. The practical objective is to reach the best reward threshold consistently, not to pursue a larger number for its own sake.
Daeva Bio-Research Base Enhance Stone Rewards by Score
Enhance Stones are awarded according to the highest score threshold reached during the run. The reward does not increase by exactly one stone for every additional point. Instead, the current client lists a sequence of fixed payouts. This distinction is important when deciding whether another kill in the last few seconds is worth the effort.
| Minimum Final Score | Enhance Stones |
|---|---|
| 100 | 3,000 |
| 200 | 3,200 |
| 300 | 3,400 |
| 400 | 3,600 |
| 500 | 3,800 |
| 1,000 | 4,000 |
| 1,500 | 4,300 |
| 2,000 | 4,600 |
| 2,500 | 4,900 |
| 3,000 | 5,200 |
| 3,500 | 5,500 |
| 4,000 | 5,800 |
| 4,500 | 6,100 |
| 5,000 | 6,400 |
| 5,500 | 6,700 |
| 6,000 | 7,000 |
| 6,500 | 7,300 |
| 7,000 | 7,600 |
| 7,500 | 7,900 |
| 8,000 | 8,200 |
| 8,500 | 8,500 |
| 9,000 | 9,000 |
| 9,500 | 9,500 |
| 10,000 | 10,000 |
A score of 8,000 awards 8,200 Enhance Stones, while reaching 9,000 awards 9,000 stones. Improving from 8,000 to 9,000 points therefore adds 800 stones to that run. Repeating the same improvement across 14 standard weekly entries adds 11,200 stones to your total. These small improvements matter because every attempt draws from the same limited allowance.
At the maximum listed tier, 14 runs producing 10,000 Enhance Stones each would yield 140,000 Enhance Stones in a week. This is a theoretical total for spending all 14 standard entries on Bio-Research Base and achieving the top reward every time. It excludes additional attempts from eligible challenge tickets and should not be treated as a guaranteed result for every character.
How to Improve Your Score Without Expensive Gear
Before buying major upgrades for this dungeon, identify where the points are being lost. A character with adequate damage but poor movement may gain more from a mobility adjustment than from a costly weapon change. A character that crosses the arena quickly but takes too long to defeat elites has the opposite problem. Review your score together with what happened during the run instead of judging performance from Item Level alone.
If Normal Enemies Take Too Long
Improve the efficiency of your area-damage rotation. Try to hit several subjects with each major attack and avoid using powerful area skills when only one weak target is in range. Positioning can be more important than raw damage here: an attack that defeats five enemies together saves time that five separate attacks cannot recover. Worm Carnage is a useful temporary effect to test when normal-enemy durability is clearly your main limitation.
If Elites Survive Too Long
Preserve an effective burst sequence for the yellow-marked targets. Check whether your strongest abilities are on cooldown when elites arrive, whether you are losing attacks while closing distance and whether defensive movement is interrupting your damage. Compare Elite Hunter, Slayer and Adrenaline when available. A stronger elite rotation can outperform a small increase in normal-enemy kills because each elite contributes 1,000 points.
If Movement or Survival Is the Problem
Use shorter, deliberate paths between groups and avoid repeatedly crossing the entire arena without a target. Movement skills are valuable when they help you reach an elite, but spending every mobility cooldown while clearing low-value enemies can leave you stranded at the wrong moment. If turret projectiles or enemy attacks regularly interrupt you, prioritize more reliable positioning before assuming that another offensive upgrade will fix the run.
For a newly unlocked character, consistent intermediate scores are a reasonable starting point. Your immediate goal should be reaching the next listed payout, such as moving from 5,500 to 6,000 points, rather than assuming a 10,000-point result is realistic before your build can defeat elites efficiently.
How to Use Instant Clear Tickets Efficiently
After completing Daeva Bio-Research Base, the Instant Clear system can save time on repeated runs. An Instant Clear Ticket: Daily Dungeon (Bound) allows an eligible clear without replaying the full 90-second encounter. However, it does not create a free additional attempt. Each instant clear consumes a ticket and an available Daily Dungeon entry, so the score and reward shown in the interface matter just as much as they do during a manual run.
The sensible approach is to establish a strong manual score before spending several tickets. Instant Clear rewards are tied to the qualifying clear result used by the system. Check the displayed reward before confirming a batch, especially if your latest run performed worse than your previous one. A ticket saves time, but repeating a low-value payout across several limited entries can cost more Enhance Stones than the minutes saved are worth.
The October 28, 2026 Global update changed the listed weekly purchase limit for Instant Clear Ticket: Daily Dungeon (Bound) to 14 per server, at 30,000 Kina each. The update also adjusted its placement between the Wind Breeze Merchants shop and the corresponding Substance Morph section. Check the current in-game menu and your account's access before purchasing; older guides that still describe a seven-ticket weekly shop limit do not reflect that update.
Bio-Research Base vs Odylium Repository: Where Should You Spend Entries?
Since the October 28 Global update, Daeva Bio-Research Base is not the only available Daily Dungeon using the Unknown Fissure counter. Odylium Repository shares the same standard weekly entry allowance, but its main reward is Soul Crystals for Genus Insight progression. Bio-Research Base awards Enhance Stones for equipment enhancement. You therefore need to decide which progression system benefits most from your remaining entries.
If upgrading your weapon or armor is your immediate bottleneck, Bio-Research Base is the more direct choice. If you already have enough Enhance Stones but cannot advance your Genus Insight boards, Odylium may provide more useful materials. It is also reasonable to split the 14 standard entries between the two dungeons instead of committing an entire week to one resource.
For a breakdown of the alternative reward system, see our AION 2 Odylium Repository Guide. That guide focuses on Soul Crystal rewards and their uses; the strategy here focuses specifically on defeating Bio-Research Base test subjects and maximizing Enhance Stone payouts.
Common Mistakes That Lower Your Daeva Bio-Research Base Score
Most disappointing runs are not caused by one disastrous mistake. They usually lose a few seconds repeatedly until the player misses an elite or falls short of a reward threshold. Correcting those repeated losses is often easier than buying substantially better equipment.
- Ignoring elite markers: Spending too long on normal enemies can cost a 1,000-point elite opportunity.
- Chasing isolated enemies: A single low-value target rarely justifies a long detour when grouped enemies or elites are available.
- Using burst skills on weak packs: Saving a suitable cooldown for elites can improve overall points per second.
- Always picking the same type of buff: A movement bonus cannot solve weak elite damage, while more Attack may not fix excessive travel time.
- Standing still under turret fire: Repeated projectile damage and defensive interruptions reduce your active damage time.
- Ignoring score thresholds: Falling just short of the next reward band can waste a reachable payout increase.
- Using Instant Clear too early: Repeating a weak reward with tickets consumes entries that could have produced more stones.
- Forgetting the shared entry pool: Spending every attempt on one Daily Dungeon leaves none of the standard allowance for the other.
- Following outdated entry or ticket advice: Older guides may show previous shop limits or treat Odylium Repository as unavailable.
Daeva Bio-Research Base FAQ
These answers cover the entry and reward details that most directly affect farming decisions. Score values and reward thresholds below reflect the Global client data extracted on October 28, 2026; the live interface should be checked again after future changes.
How Many Enhance Stones Can You Get Per Run?
The current reward table starts at 3,000 Enhance Stones for a score of at least 100 and reaches 10,000 Enhance Stones at 10,000 points. Intermediate scores receive the fixed payout for their highest completed threshold. A run does not need to reach the maximum score to provide useful materials, but a consistently higher score makes better use of limited entries.
Do Alternate Characters Get Extra Daily Dungeon Entries?
Not from the standard allowance on the same server. The current Unknown Fissure counter provides 14 weekly entries per server, shared between characters and the available Daily Dungeons that use it. Eligible challenge tickets can add attempts separately, but changing characters on the same server does not reset the normal counter.
What Is the Best Buff for Reaching 10,000 Points?
Elite Hunter is particularly attractive when elite durability limits your score, while Slayer and Adrenaline can provide strong offensive value depending on your build. Footwork may be better if you already defeat enemies quickly but lose time reaching corner spawns. Choose according to the weakness visible in your previous runs rather than treating any one effect as universally optimal.
Can You Farm Enhance Stones with Instant Clear?
Yes, provided you have the required Instant Clear Tickets and eligible Daily Dungeon entries. Instant Clear replaces the manual replay; it does not bypass the entry counter. Establish a strong qualifying score, verify the reward displayed in the interface and then use tickets for repeat clears if the Kina and ticket cost make sense for your account.
Conclusion
AION 2 Daeva Bio-Research Base rewards disciplined target selection more than aimless enemy clearing. Build your 90-second strategy around yellow-marked elites, use area attacks on tightly grouped normal subjects and choose temporary buffs that address your actual limitation. Track the next Enhance Stone reward threshold, improve your manual score before purchasing repeated Instant Clears and remember that your weekly Unknown Fissure entries are shared with Odylium Repository. A consistent route that earns a few hundred extra points every run can turn into thousands of additional Enhance Stones over the week.
