This spell calls into existence a shard of prismatic energy, much like a chunk off of a prismatic wall. The shard itself is about two feet long, 4 inches at the base, and a triangular pyramid.
As protection from its brilliance, the spell grants the caster protection from its aura by giving him - for lack of a better term - magical arc welding glasses (his eyes turn deep black). All other creatures must save versus spell or be blinded for 2d4 rounds. Smoked crystal goggles will prevent this.
The caster however is blind at the end of the spell for 1d4 rounds (while his goggles fade).
This spell affects the creature struck just as walking through a prismatic sphere: all seven saving throws are rolled as per any other prism spell (that's 90 points of damage minimum, if they make every saving throw). The shard remains to wreak further havoc for its duration.
The verbal component is up to you. The material is a 5,000 gp diamond and the somatic component is guiding it with your finger. You do have to maintain concentration to keep it around (just like spiritual hammer).
