This is the ultimate suicide system. I guess many others may have their own version of megablast. The idea is that in a desperate situation, the caster bursts out all his energy in a ball of pure energy causing 1d6 of magical damage per spell levels remaining in the caster's memory (plus 9d6 for the megablast itself). Magic resistance reduces damage again by half (shock wave remains). The caster himself has a 50% chance of being disintegrated (a saving throw applies, if the saving throw is made, he still receives all damages as above), and a 50% chance of ending naked on another, random, plane.
The material component is a platinum dagger the wizard uses for suicide (good idea, ending up naked but with a platinum knife somewhere in the abyss). The dagger is obviously not consumed in the casting.
