Special Traits


  • Multiattack. The demon makes three attacks: one with its bite and two with its ranseur. It can attack with its tongue instead of making a bite attack.
  • Bite. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 17 (2d10 + 6) piercing damage.
  • Ranseur. Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 20 (4d6 + 6) piercing damage.
  • Tongue. Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 15 (2d8 + 6) slashing damage, and the target is grappled (escape DC 16). Until this grapple ends, the target is restrained, and the demon cannot attack with its tongue.
  • Combustible Spittle (Recharge 5-6). The demon spits a line of acid in a 30-foot line that is 5 feet wide. Each creature in that line must make a DC 17 Dexterity saving throw, taking 27 (6d8) acid damage on a failed save, or half as much on a successful one. At the start of the demon’s next turn, the acid ignites and any targets hit by it burst into flames, taking 10 (3d6) fire damage per round until extinguished.


This creature appears as a massive, squat and bloated frog-like creature with arms in place of its forelegs. Two large horns protrude above deep sunken eyes.

Greruors serve in the infernal armies of several demon lords, particularly Tsathogga. They are strong, powerful, and brutal demons that delight in inflicting pain on others. They are extremely loyal and follow orders without question. Some greater demons, like nalfeshnees and glabrezus, relish the flesh of greruors’ legs and often organize hunting parties to track and slay the frog demons. The greruors, however, are not the weakminded brutes they appear to be and often win such confrontations using their deadly ranseurs and their large numbers to turn back their opponents.

A greruor appears as a massive, squat, bloated, frog-like demon with arms in place of its forelegs. Its wide, frog-like head has two 3-foot-long horns protruding just above its deep, sunken eyes. It moves by hopping on its rear legs. Its arms end in talons which are usually clutched around the greruor’s deadly ranseur. Its huge mouth sports razor-sharp teeth of a dull gray color. The greruor stands about 8 feet tall when on all fours.

In combat, they stand on their hind legs and attack with their ranseur.

The greruor’s flesh is greenish-brown mottled with red or gray. Its skin constantly oozes and secretes a thick, mucus-like clear slime that is slick to the touch.

Greruor’s enjoy combat and seek it wherever they can find it. Normally they rely on their natural attacks, combustible spittle, and weapons to fell opponents. If outmatched, they use confusion to disorient the strongest opponent and hold person on humanoid casters, followed closely by shatter on grouped foes. Grappled opponents are often held in the mouth of one greruor while another stabs the victim with its ranseur.
