Rotbomber

Disgusting and dangerous, rotbombers bound around on all four limbs, ripping off the pressurized and explosive necrotic pustules that grow out of their backs to lob them toward their enemies. When they explode, the pustules emit concussive blasts of force and deadly pestilence that can infect a victim. Though slow and overburdened by the intense weight of the pustules, rotbombers can move with a surprising speed when they need to hunt down their quarry.
