Special Abilities
Pack Tactics. The emperor's hyena has advantage on attack rolls against a creature if at least one of the hyena's allies is within 5 feet of the creature and the ally isn't incapacitated.
Stench. Any creature that starts its turn within 5 feet of the emperor's hyena must succeed on a DC 12 Constitution saving throw or be poisoned until the start of its next turn. On a successful saving throw, the creature is immune to the emperor's hyena's Stench for 24 hours.
Turning Resistance. The emperor's hyena has advantage on saving throws against any effect that turns undead.
Actions
Multiattack. The emperor's hyena makes two bite attacks.
Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) piercing damage plus 10 (3d6) necrotic damage.
Black Breath (Recharge 5-6). The emperor's hyena breathes a 15-foot cone of noxious black vapor. Each creature in the area that isn't an undead or a construct must make a DC 12 Constitution saving throw, taking 14 (4d6) necrotic damage on a failed save, or half as much damage on a successful one. If the saving throw fails by 5 or more, the creature gains one level of exhaustion. This exhaustion lasts until the creature finishes a short or long rest.
