Sister Clara gasped as she tried to speak and nothing but demonic utterances issued forth.[1]

Curse of Tongues, or CoT, is a warlock Affliction ability which increases the enemy's casting time.

Curse of tongues allows the caster to steal the target's voice with a curse, replacing it with the voice of a terrible demon. The subject's new voice only speaks in the Eredar tongue, regardless of any other spells or effects on the target. This spell prevents the target from using any spell with verbal components. [2]

Targets affected by this spell will actually speak in Demonic in emotes and in chat. A CM on Blizzard's official forums joked about how coders spent time coding this curse to do just that.

Talent improvement

Suppression reduces the chance for the curse to be resisted; Grim Reach increases the range; and Contagion reduces the chance that it'll be dispelled.

Tips and tactics

CoT is used primarily against casters to limit their spellcasting ability.

Mages can remove curses and the talented ones will do so.
