An ailment is a detrimental effect associated with one or more damage types. Ailments are similar to debuffs, but they are not synonymous. The most notable difference is that ailments are typically inflicted by hits made up of their associated damage types, whereas debuffs are applied by skill effects.
Ignite, chill, freeze, shock, scorch, brittle, and sap are referred to as elemental ailments because they are associated with elemental damage types. Bleeding and poison are non-elemental ailments.
