Blisterbomb Centipede

Illumination. The centipede sheds bright light in a 10-foot radius and dim light for an additional 10 feet.

Blood Embers. When the centipede takes damage of any kind except psychic or fire, each creature within 5 feet of it takes 2 (1d4) fire damage.

Blisterbomb. When the centipede is reduced to zero hit points, it must make a DC 10 Constitution saving throw. On a successful save, the centipede explodes, creating a 5-foot radius sphere dust cloud that obscures the area. On a failed save, the centipede explodes, instead creating 5-foot radius sphere fireball. Each creature in that area must succeed a DC 11 Dexterity saving throw, taking 5 (2d4) fire damage and 5 (2d4) poison damage on a failed save, or half as much on a successful one.

Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one creature. Hit: 4 (1d4 + 2) piercing damage, and the target must succeed on a DC 11 Constitution saving throw or take 10 (3d6) poison damage. If the poison damage reduces the target to 0 hit points, the target is stable but poisoned for 1 hour, even after regaining hit points, and is paralyzed while poisoned in this way.
