Torment

Torment is a single target damage spell, one of the four abilities of the Voidwalker warlock minion, learned automatically at level 10.

Despite the tooltip reading Shadowstrike, it appears Torment simply deals shadow damage.

With Mists of Pandaria, Torment no longer generates bonus threat. Instead, Voidwalkers rely on Threatening Presence in conjunction with Torment and basic melee attacks to maintain aggro.
