If you play these small drums while casting a spell with a random effect, such as Prismatic Spray or Confusion, you may re-roll the effect, but you must take the new result. This power may be used three times per day.
Once per day, you can play these drums while casting a damaging spell of 6th level or lower. The spell will deal 50% more damage against chaotic creatures, and half damage against other creatures.
