Bane (spell)

Banes are Warlock debuffs. All Banes cause the target to take damage, although each has a different way of achieving this, and some have additional effects.

Only one Bane per warlock can be active on any one target. In addition, Bane of Doom and Bane of Havoc can only be active on one target at a time (per warlock), so warlocks much choose which Bane to inflict upon which target.

Banes are of the Curse dispel type, and so can be dispelled by Druids, Mages and Shamans.

All Banes are instant cast, have a 40yd range and no cooldown.

Curses and Banes
Bane spells were implemented in Patch 4.0.1, to differentiate them from Curses. They are made up of many of the former Curse spells. Only one Bane and one Curse can be active on any target at a time (per warlock).
