Wrath of the Hold

Your tattoos carry the strength of an innumerable horde, and you can expend one use of your storied skin's Living History ability to animate your tattoos as ghostly assailants that swarm your foes. These spirits attack all foes in a 30-foot cone, dealing 1d6 per 2 levels spirit damage. The damage increases by 1d6 at 10th level and every 2 levels thereafter. Each affected creature must attempt a basic Will saving throw against the higher of your class DC or spell DC.
