Corrosion Damage (Chinese: 侵蚀损伤; Pinyin: Qīnshí sǔnshāng; lit. "Erosion Damage") is an Elemental Damage in Arknights, introduced in Dossoles Holiday.

Effect

After Corrosion Damage reaches 1000, the affected unit has its DEF permanently reduced by 100 and takes 800 Physical damage.
—In-game tip

Corrosion Damage's burst effect causes the victim to take 800 Physical damage and have their DEF permanently reduced by 100 which can stack without a limit (e.g. -200 on the second explosion, -500 on the fifth explosion, etc.), with a cooldown of 10 seconds.

Sources

Friendly units who are being affected by Erosion for being on tiles submerged by the High Tide will periodically receive Corrosion Damage in addition to receiving additional Corrosion Damage when attacked.
