  • Carrion Stench. Any creature other than an undead hyaenodon that starts its turn within five feet of the undead hyaenodon must succeed on a DC 14 Constitution saving throw or be poisoned until the start of the creature’s next turn. On a successful saving throw, the target is immune to the Stench of all undead hyaenodons for one hour.


  • Multiattack. The undead hyaenodon makes one Bite attack and one Claw attack.
  • Bite. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 15 (2d10 + 4) piercing damage and the creature must succeed on a DC 14 Strength saving throw or become grappled by the hyaenodon (escape DC 14). The undead hyaenodon can grapple only one creature at a time.
  • Claw. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) slashing damage.
  • Shake. The undead hyaenodon shakes a grappled target, inflicting 16 (3d10) slashing damage.


The most favored priests of the gnoll gods are gifted with an undead hyaenodon servant. These reanimated hyenas from a bygone era are the size of a horse, with huge jaws that make up most of their rotting heads. Cruelly intelligent, they serve their masters, and only the most foolish priests think those masters are mortal and not gnoll gods.
