Corruption

Corruptions on The Watcher

A Corruption (also called a Corruption effect) is a buff that is applied (typically self-applied) to a mob or creature. Corruptions can be removed using Corruption removal skills, of which all Character classes have at least one.

Many boss fights in dungeons/raids require efficient and timely Corruption removal in order to be successful. Corruptions can be recognized by "Resistance: Corruption (Level)" in the effect tooltip.
