Elemental Damage is a gameplay mechanic in Arknights.


Certain enemies are capable of inflicting Elemental Damage "build-up" to friendlies through various methods. Should a friendly unit's Elemental Damage build-up reaches a certain threshold, the unit will receive various negative effects depending on the type of the Elemental Damage inflicted. When a unit's Elemental Damage build-up reaches maximum, it will deplete itself over 10 seconds during which the unit will not receive any further Elemental Damage build-up.

Wandering Medics remove Elemental Damage build-up as they heal friendly units, which they will do even on those with full HP.

  • The way Elemental Damages work is similar to status ailments in "Souls-like" games (Dark Souls series, Bloodborne, Sekiro: Shadows Die Twice, and Elden Ring).
  • There exists in the current Chinese version an as of yet unused "flag" — a trait that can be applied to a unit in code — giving the recipient immunity to Elemental Damage, making them unable to receive any. The flag is called "ELEMENT_FREE_ALL" in the code.
