Bombs are volatile creatures from the Elemental Plane of Fire, so named for their tendency to literally explode if sufficiently injured or agitated. Hot-tempered and dim-witted, they occasionally find their way to the Prime Material Plane, where they delight in setting anything they can ablaze. Living Fireballs. A bomb resembles a living ball of semi-solid flame, with two stubby arms protruding from the lower body and a face locked in a permanent sharp-toothed, maniacal grin.
