Special Traits

• Charge. If the hippomonokeros moves at least 20 feet straight toward a target and then hits it with a horn attack on the same turn, the target takes an extra 9 (2d8) piercing damage. If the target is a creature, it must succeed on a DC 16 Strength saving throw or be knocked prone.
• Relentless (Recharges after a Short or Long Rest). If the hippomonokeros takes 10 damage or less that would reduce it to 0 hit points, it is reduced to 1 hit point instead.
• Sudden Rush. Until the end of the turn, the hippomonokeros’ speed increases by 120 feet and it doesn’t provoke opportunity attacks.

Actions

• Multiattack. A hippomonokeros makes three attacks: one with its horn, one with its bite, and one with its hooves.
• Horn. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 9 (1d8 + 5) piercing damage and the target must make a DC 14 Dexterity saving throw or takes a permanent and cumulative ?1 penalty to the AC of any armor or shield it is wearing. Armor reduced to an AC of 10 or a shield that drops to a +0 bonus is destroyed.
• Bite. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 9 (1d8 + 5) piercing damage. If the target is a creature, the hippomonokeros can choose to deal no damage with the attack to disarm the target. The target must succeed on a DC 16 Strength saving throw or drop one item it is holding on the ground.
• Hooves. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 12 (2d6 + 5) bludgeoning damage.

About

This creature, which looks like a form of wild ass, is as big as a horse. Its body is white except for the head, which approaches purple, while its eyes give off a dark blue color.

It has a horn on its forehead two feet long; the lower part of the horn is white, the upper part is crimson, while the middle is jet-black. A typical adult hippomonokeros grows to 8 feet in length, stands 5 feet high at the shoulder, and weighs 1,200 pounds. Females are slightly smaller and slimmer than males. Their flesh is inedible.

A Deadly Panacea. Hippomonpkeroi are incredibly fast unicorns capable of fiercely defending themselves, and for good reason–their horns are a panacea for poisons, disease, and even bestow fire resistance. Hippomonokeroi cannot be taken alive; they fight to the death to protect their foals.

Fierce Combatants. A hippomonokeros’ horn is practically indestructible, and when pitted against manmade armor are capable of destroying them. In addition to their wicked kicks, hippomonokeroi can use their teeth to tear weapons out of the grasp of their opponents.
