Spell Lock

Spell Lock is a warlock Felhunter ability granted by Command Demon. When used while the target is in the process of casting a spell, the target will be unable to cast a spell from the same school of magic for 6 seconds. This is an instant-cast ability with a 24-second cooldown, and is learned automatically by the Felhunter at level 50.

Use of this skill will usually force an NPC caster to enter melee combat, where they are at a considerable disadvantage.

This is an excellent tool against any caster class, and is particularly useful for finishing-off healers, especially when combined with other abilities such as Fear and Death Coil (warlock ability) to provide a lengthy period of silence.
