When used on a monster that is not currently assigned or on a monster that is unaffected, the ability will deal 30–110% ability damage and administer a 15 second cooldown. Monsters that cannot be tagged are unaffected by Tuska's Wrath, even when on a Slayer assignment. In general, this means bosses are unaffected by the Slayer task bonus.
The damage cap of this ability is 15,000 life points. Against a slayer target, the attack will always be treated as critical, severely weakening or killing the slayer target when used against them.
Upon release, there was a bug where players assigned on a task with an untaggable monster who used the ability would only deal 110% weapon damage and administered a 120 second cooldown. This was fixed with the Patch Notes of 15 June 2015.
The appearance of the ability is based on the factions' god spears in Tuska Comes. The spear appearing in the animation is random, making it the first ability with a varying animation.
During the world event, this ability was available for 4,000 Reward Currency.
