Keen Smell. The onikage has advantage on Wisdom (Perception) checks that rely on smell.


Hooves. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) bludgeoning damage plus 7 (2d6) poison damage.

Bite. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 20 (3d10 + 4) piercing damage, and the target is grappled (escape DC 16). Until this grapple ends, the target is restrained, and the onikage can’t bite another target.

Tail. Melee Weapon Attack: +6 to hit, reach 10 ft., one target not grappled by the onikage. Hit: 13 (2d8 + 4) bludgeoning damage. If the target is a creature, it must succeed on a DC 16 Strength saving throw or be knocked prone.

Ethereal Stride. The onikage and up to three willing creatures within 5 feet of it magically enter the Ethereal Plane from the Material Plane, or vice versa.


Onikage, or demon horse, are mounts used by oni and their servants to travel between Spirit Realms and for cavalry.  These horses are demonic undead creatures with scaled, horse-shaped bodies, long fangs, crocodilian tails, glowing eye sockets, and clawed hooves. They range from dark green to bruise-purple, with tentaclelike manes of contrasting color.

Onikages hunger for living flesh, and if they are alone they attack any living creature without thought or fear. These foul creatures often serve as mounts for still worse oni allies, however, and learn to bring their instinctive hunger under control when they carry a rider. Onikage are most often found serving as mounts for maho-bujins, akutsukai, or akutenshi.
