While playing this accordion with both hands, you may use your action to take control of up to 3HD worth of undead creatures within 30 ft. While controlled, the undead will follow simple commands which you convey magically through the music. You may maintain this control on subsequent turns using your action.  The control ends when the music ends, or if the undead are destroyed or turned.

Notes: must be proficient in a musical instrument, Control, Instrument
