How do I counter the corrosion effect in Floor 11 of Genshin Impact?

The corrosion effect in Floor 11 of the Spiral Abyss is one of the most challenging mechanics players face. Corrosion is a debuff applied by certain enemies, such as Rifthounds and Rifthound Whelps, which causes your entire team to lose HP over time, regardless of whether they are on the field or not. This effect bypasses shields, making it particularly dangerous. To counter corrosion effectively, you need a combination of healing, team composition adjustments, and strategic gameplay.

First, letÔÇÖs break down the mechanics of corrosion. When you are hit by a Rifthound or Rifthound Whelp attack, your active character and all off-field characters will start losing HP periodically. This effect stacks, meaning the more times you are hit, the faster your teamÔÇÖs HP will drain. Unlike other debuffs, corrosion cannot be cleansed by abilities like BennettÔÇÖs burst or JeanÔÇÖs burst, so healing is the only way to mitigate its effects. Additionally, corrosion ignores shields, so characters like Zhongli or Diona, who rely on shielding, will not be able to protect your team from this damage.

To counter corrosion, the most important step is to include a strong healer in your team. Characters like Kokomi, Barbara, Qiqi, or Jean are excellent choices because they provide consistent healing over time. Kokomi and Barbara are particularly useful because they can heal the entire team with their elemental bursts, while Qiqi and Jean offer both healing and utility. Bennett is also a good option, but keep in mind that his healing only affects the active character, so youÔÇÖll need to rotate through your team to heal everyone.

When building your team, consider pairing your healer with characters who can deal consistent damage and apply crowd control. For example, a team with Kokomi as the healer, Kazuha for crowd control, and two DPS characters like Ayaka and Raiden Shogun can work well. This setup ensures that you have both healing and damage output to handle the enemies efficiently. Another effective team could include Jean as the healer, paired with Xiao for Anemo resonance, and two other DPS characters like Hu Tao and Xingqiu. This team benefits from JeanÔÇÖs healing and XiaoÔÇÖs high damage output.

Artifact and weapon choices are also crucial for surviving corrosion. For healers, prioritize artifacts that increase healing effectiveness, such as the Maiden Beloved set or the Ocean-Hued Clam set. Kokomi, for example, benefits greatly from the Ocean-Hued Clam set, which converts her healing into damage. For weapons, focus on those that boost healing or energy recharge, such as the Prototype Amber for Kokomi or the Favonius Sword for Jean. For DPS characters, stick to their usual artifact sets, such as Emblem of Severed Fate for Raiden Shogun or Blizzard Strayer for Ayaka, but ensure they have enough HP and defense to survive the corrosion damage.

In terms of gameplay strategy, the key is to avoid getting hit by Rifthounds as much as possible. Use crowd control abilities to keep them at bay and focus on taking them out quickly. Characters like Venti, Kazuha, or Sucrose can group enemies together, making it easier to deal AoE damage. Additionally, try to dodge their attacks by paying attention to their animations. Rifthounds often telegraph their moves, so learning their patterns can help you avoid unnecessary damage.

One common mistake players make is relying too heavily on shields. While shields are useful in many situations, they are ineffective against corrosion. Instead, focus on healing and damage mitigation through dodging and crowd control. Another mistake is neglecting to heal off-field characters. Since corrosion affects the entire team, make sure to rotate through your characters and use your healerÔÇÖs abilities to keep everyoneÔÇÖs HP up.

Advanced techniques include using energy management to ensure your healerÔÇÖs burst is always ready. For example, with Kokomi, you can use her elemental skill to generate energy particles and heal your team while waiting for her burst to recharge. Similarly, with Jean, you can use her elemental skill to group enemies and generate energy, ensuring her burst is available when needed.

In summary, countering corrosion in Floor 11 requires a strong healer, careful team composition, and strategic gameplay. Focus on healing, avoid relying on shields, and use crowd control to minimize damage. With the right setup and approach, you can overcome this challenging mechanic and clear the floor successfully.
