Act of Treason

You choose a creature within range, a mask of the Rakdos guild appears on their face cloaked in fire. The creature must succeed on a Charisma saving throw, on a failed save they are filled with traitorous rage. Until the spell ends on each of their turns they must move towards and attack the nearest ally with their most powerful attack or cantrip. When the spell ends the mask turns to ash and fades away.
