When the brimstone smoke clears, a legion of devils awaits your command.

Daily  
Standard Action      Close burst 3

Effect: You call forth four legion devil legionnaires, each appearing in an unoccupied you choose within the burst. These devils act according to your orders (free action) on your initiative count, and they gain a +2 bonus to attack rolls as long as you are conscious and alive. Each devil remains until it is killed, until you dismiss it (a free action), or until the end of the encounter.
