SQ Float, Self-Destruct
A king bomb has the Float (always floating 5 feet into the air) status effect continuously unless unconscious or dead. This effect cannot be dispelled.
After the king bomb reaches 0 hit points or lower, it explodes as an immediate action, destroying itself and dealing 16d6 points of elemental type and physical (half & half) damage to everything within a 30-ft.-radius (Reflex save DC 23 for half dmg). After its own destruction it creates 1d6+1 T1 bombs in its place. Blue mages may learn this ability as a 1st level spell (Knowledge: Planes DC 17).
