Changes: Debuff

Revision as of 17:45, 2 June 2009

A debuff is the contrary 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.^[1]

Sometimes the term debuff is also used to describe the act of removing buffs on hostile targets, but it is better to refer to such an action as a dispel or cure after the common spells that remove such effects. Another popular name for removing debuffs is decurse.

A good example for a multi-function debuff is the [Hunter's Mark]. All attackers on that target gain increased ranged attack power; additionally the target cannot hide from the Hunter, no matter if they stealth, turn invisible, or morph into beast form. Hunter's Mark, being in the Arcane school, is removable with Cloak of Shadows and other skills and talents which remove magical debuffs.

Debuffs come in many varieties and most of them are race/class specific spells or abilities.

Debuffs are also color coded, with poison debuffs having a green border, magic debuffs a blue border, physical debuffs a red border, diseases a brown border, and curses a purple border.

Limitation

According to an forums post by Daelo, the Lead Encounter Designer, there is no effective limit on the number of debuffs that may be applied to a creature at one time.^[2] Prior to the release of the Wrath of the Lich King expansion, a single target could have at most 40 debuffs at one time.^[3]

Similar debuffs generally do not stack with eachother.^[4] One prominent exception is damage over time debuffs, multiple copies of the same damage over time debuff from the same character generally don't stack with eachother, however multiple damage over time debuffs from the same character and multiple copies of the same damage over time debuff from different characters will generally stack.

Examples of Debuffs

Dispelling Debuffs

A list of types of debuffs, the classes that can remove them and the earliest level that class gains the ability.

Poison: Paladin (8), Druid (14), Shaman (16),
Disease: Paladin (8), Shaman (22), Priest (22)
Magic: Priest (18), Warlock [Felhunter] (30), Paladin (42)
Curse: Mage (18), Druid (24), Shaman (Resto talent, 40)

Examples of Abilities that Cure or Dispel

Druid: [Remove Curse], [Abolish Poison]
Mage: [Remove Lesser Curse]
Paladin: [Cleanse] (Cures Disease, Poison and Magic)
Priest: [Dispel Magic], [Abolish Disease]
Shaman: Cure Poison, Cure Disease, [Cleanse Spirit]

Unclassified Debuffs

Some debuffs are not classified in any way, and as such can not be dispelled by any class. There are some exceptions to this - some Bleed effects, which are unclassified, can be cured by using a [Luffa] or the Dwarven racial ability [Stoneform]. Also, Paladins can dispel nearly any debuff on themselves by using [Divine Shield], as can Mages by using [Ice Block].
