bag of cataclysm

a simple brown leather bag with drawstring, once opened a miniature elemental cataclysm erupts from within to grant the holder the power of the elements, you don't know if someone captured a cataclysm in a bag of holding, or was able to reproduce the the makings of the creature on a smaller scale, but you do know they had to be really crazy or really smart.

roll a d4 to choose which element will be used 1=fire, 2=water, 3=earth, 4=wind, all attacks make a 15ft cone and upon making a hit a target will receive 2d6 damage respectively to the element that was rolled.

Notes: must be calm in the face of any natural disaster.
