Chaos Cataclysm

Locking on to a single target, you invoke the accumulated dissonant chaos surrounding the realms concentrating its output on a single area. 

The target makes a Intelligence Saving Throw against the casters spell save dc. Targets that fail the saving throws take 10 d8, 6 d10 and 2 d12 of three different damage types that are randomly rolled for by the DM, and half that on a success. 

After invoking the Chaos, wielder makes a Unmodded Save (Dc 10), or have the casters hp maximum cut by half, and rendered unconscious for an hour.
