Characters being **Corroded** will lose a **% of their HP** every second. Active characters can be brought down by **Corrosion**. When a non-active character's HP is **less than 15%**, they will no longer lose HP due to **Corrosion**. **Corrosion** lasts 10s and can stack. The duration of each stack is counted independently. ## General Tips **Corrosion** will deal significant damage to your team. Make sure to have at least one healer for each side. You may even consider 2 healers if they are not particularly invested. Enemies on each floor in general are fairly easy and **Corrosion** ends up being the most threatening thing. In most chambers, you'll want to simply aim for the enemy with the **Smoldering Flames** aura. **Corrosion** builds up faster if you kill enemies faster. Take your time and kill enemies slowly to prevent quick buildup of **Corrosion**. Don't forget you also have 5 minutes for 3★ on the first chamber so you don't have to rush. The damage required to actually clear the floor is not very high - you're more likely to die from **Corrosion** than to run out of time. Characters that can heal your entire team at once (like **Barbara, Jean**) or strong off-field healers (like **Bennett, Qiqi**) are preferred over characters that mostly rely on shields (like **Diona**). It may help to bring characters than can **cleanse** the **Smoldering Flames** aura (see [Removing Debuffs](/abyss/mechanics/debuffs/removing-debuffs.md)). There is an enemy in each chamber with this aura and when combined with **Corrosion** can cause a large amount of damage to the active character. If you only have access to one of these characters, but them on **Side 2**, as the enemies with the aura are tankier and you're less likely to be able to avoid it. Avoid using characters like **Xiao** and **Hu Tao** that already drain their own **HP.** ## Corrosion {% embed url="" %} Killing an enemy adds a stack of Corrosion {% endembed %} {% embed url="" %} Characters affected by Corrosion lose HP {% endembed %} Since each stack of **Corrosion** is independent, the faster you kill enemies, the faster your **HP** will drop. Off-field characters will never die from **Corrosion**, so you if you can make sure your active character stays at good health then you can ignore healing the rest of your team. **Corrosion** drains about **0.75% of Max HP** per second per stack. For some perspective, killing a wave in the first Chamber (5 enemies) will drain about **37.5% HP** from all characters over the **10 second** duration. ## Team Recommendations | | Side 1 | Side 2 | | -------------------------- | :----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------: | :----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------: | | **Shieldbreakers** | ![](/files/-MVEZ5et1q2zAFejhRrn)![](/files/-MVEZ5eqD2mIb0RfP0a8) | ![](/files/-MVEZ5eqD2mIb0RfP0a8) | | **Preferred DPS Elements** | ![](/files/-MVEZ5esQt4NA9KRz7r5) | ![](/files/-MVEZ5eqD2mIb0RfP0a8)![](/files/-MVAsblvjDGgQ7zw1WTd) | | **Avoid DPS Elements** | ![](/files/-MVEZ5et1q2zAFejhRrn) | ![](/files/-MVEZ5et1q2zAFejhRrn) | | **4**★ **Supports** |

It can be difficult to kill the **Pyro Abyss Mage** before it emits it's aura, so having a **cleanse** for **Smoldering Flames** is helpful here (see [Removing Debuffs](/abyss/mechanics/debuffs/removing-debuffs.md)). The **Dendro Samachurl** here is particularly dangerous, so try to take it out first. Not only will it block your path with thorns, but if it applies![](/files/-MVArPJb-qvd63m0tky2)on you, all the remaining enemies can cause **Burning**, adding yet another DoT onto your active character. ## Chamber 2 **Monster Level - 90** ### Side 1 ![](/files/-MjlyjdW25biuhdAY30p) | | | | | --------------------------------------------------------- | ---------- | --------------------------------------------- | | **In Depth Guide** | Other Info | | | [Pyroslinger](/abyss/monsters/fatui/pyroslinger.md) | | | | Smoldering Flame ([Debuffs](/abyss/mechanics/debuffs.md)) | | 721![](/files/-MVEZ5et1q2zAFejhRrn)DMG / Tick | Waves spawn in the Front > Back > Front side of the arena, in that order. Focus the **Pyroslinger** first. If you can stagger him effectively, you will not need to bring![](/files/-MVEZ5eqD2mIb0RfP0a8)for shieldbreaking on this team either. ### Side 2 ![](/files/-Mjlyl1xGxiy8qgSz4s9) | | | | --------------------------------------------------------- | --------------------------------------------- | | **In Depth Guide** | Other Info | | [Kairagi](/abyss/monsters/samurai/kairagi.md) | | | Smoldering Flame ([Debuffs](/abyss/mechanics/debuffs.md)) | 721![](/files/-MVEZ5et1q2zAFejhRrn)DMG / Tick | Waves spawn in the Front > Back > Front side of the arena, in that order. It can be difficult to kill the **Fiery Might Kairagi** before it emits it's aura, so having a **cleanse** for **Smoldering Flames** is helpful here (see [Removing Debuffs](/abyss/mechanics/debuffs/removing-debuffs.md)). You can either go for the **Kairagi** first to make the fight easier, or go for the **Potioneers** first to group the enemies quicker, depending on your needs. ## Chamber 3 **Monster Level - 92** ### Side 1 ![](/files/-Mjlys4WPiQgoOrzFCyF) | | | | ----------------------------------------------------------------- | --------------------------------------------- | | **In Depth Guide** | Other Info | | [Pyro Agent](/abyss/monsters/fatui/pyro-agent.md) | | | [Cryo Cicin Mage](/abyss/monsters/fatui/cryo-cicin-mage.md) | | | [Electro Cicin Mage](/abyss/monsters/fatui/electro-cicin-mage.md) | | | Smoldering Flame ([Debuffs](/abyss/mechanics/debuffs.md)) | 758![](/files/-MVEZ5et1q2zAFejhRrn)DMG / Tick | Waves spawn in the Front > Back side of the arena, in that order. The **Cicin** flies spawned by both the **Cryo/Electro Cicin Mages** will add to your **Corrosion** stacks. While you cannot prevent the **Electro Cicin Mage** from summoning flies, if you can stagger the **Cryo Cicin Mage** immediately it will prevent her from summoning flies. **Crowd Control** effects are extremely effective here, as it prevents the **Cicin Mages** from teleporting and hurting your clear time. If you have access to![](/files/-MVEZ5eufuBMc_rgR7X9)units like **Venti**, make sure they are on this side. You can also try to use **Freeze** teams around characters like **Ayaka** to keep them locked in place. ### Side 2 ![](/files/-Mjlyts133oAiF3Y_u_k) | | | | --------------------------------------------------------- | --------------------------------------------- | | **In Depth Guide** | Other Info | | [Geovishap](/abyss/monsters/vishaps/geovishap.md) | | | Smoldering Flame ([Debuffs](/abyss/mechanics/debuffs.md)) | 758![](/files/-MVEZ5et1q2zAFejhRrn)DMG / Tick | Waves spawn in the Front > Back side of the arena, in that order. The enemies will naturally group in this chamber. When trying to go for stars, it's best to aim for the **Geovishap** as it has more HP and let the **Slimes** come to you. It also avoids **Corrosion** the longest. Since enemies on this chamber are![](/files/-MVEZ5et1q2zAFejhRrn)infused, using ![](/files/-MVEZ5eqD2mIb0RfP0a8)/![](/files/-MVAsblvjDGgQ7zw1WTd)DPS is extremely effective.
