Buff

Counterattack

When attacked, the Champion with Counterattack buff strikes back at their attacker using their Default Skill. This attack deals 75% of the normal Default Skill damage. Can only counterattack once when attacked with a Multi-hit skill. Does not counterattack in response to the enemy’s own counterattack. Does not count as a Turn.

Champions that apply it

66 champions have a skill that applies Counterattack, according to the effect lines in the game data. This lists who applies it, not how reliably: chance, duration and resistance are on each champion's page.

The description is the game's own text. It has not been tested in battle here, and the game's wording can be loose (for example about numbers that differ between versions of an effect). See Data quality for what has and has not been checked. Found a mistake? Use "Report a problem" at the bottom of the page.
