Disintegrate

Description
A thin, green ray springs from your pointing finger. You must make a successful ranged touch attack to hit. Any creature struck by the ray takes 2d6 points of magic damage per caster level (to a maximum of 40d6). Any creature reduced to 0 or fewer hit points by this spell is entirely disintegrated, leaving behind only a trace of fine dust. A creature that makes a successful Fortitude save is partially affected, taking only 5d6 points of magic damage. If this damage reduces the creature to 0 or fewer hit points, it is entirely disintegrated.
