Burning Thunder of Omnikinesis

Prerequisite(s): Level 4 of any arcane or divine spellcasting class.

From within the blazing heart of the storm, you can fold lightning into a torrent of caustic, deep-stone chemicals; you may twist glittering ice into raging steam and terrible flame; you may bend the fundamental forces of the universe into alien shapes as you desire and back again, as you see fit.

You may choose, as a reaction, to change damage that deals acid, cold, electricity, or fire damage, to one of the other three energy types. Any non-damaging effects remain unchanged unless the new energy type invalidates them; such effects are subject to GM discretion.

You can use this ability a number of times per day equal to 3 + your Constitution modifier.
