Debuff

A debuff is the opposite of a buff. It is an effect that while it persists hampers the target in some way. Among other effects, debuffs frequently lower attributes, hinder the effectiveness of the target's actions, or cause damage over time. Sometimes the term debuff is also used to describe the act of removing buffs on hostile targets.

Controllers use debuffs on enemies for group support.

There are three main debuffs:
 * Damage Debuff
 * Healing Debuff
 * Damage Output Debuff
