Chaos Splinter

You create a splinter of chaotic energy. On a hit, it does 2d4 damage. The damage type is equal to one of the number rolled on the d4 (you can choose). If you roll the same number on each d4, it does whatever damage type you want, even if it is not on the table.

This spell's damage increases by 1d8 when you reach 5th level (2d4+1d8), 11th level (2d4+2d8), and 17th level (2d4+3d8).
