  • Charge. If the obsidian minotaur moves at least 10 feet straight toward a target and then hits it with a Gore 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 pushed up to 10 feet away and knocked prone.
  • Immutable Form. The minotaur is immune to any spell or effect that would alter its form.
  • Magic Resistance. The minotaur has advantage on saving throws against spells and other magic effects.
  • Magic Weapons. The minotaur’s weapon attacks are magical.


  • Multiattack. The obsidian minotaur makes one Gore attack and two Claw attacks.
  • Gore. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 14 (2d8 + 5) piercing damage plus 7 (2d6) fire damage.
  • Claw. Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 12 (2d6 + 5) slashing damage plus 7 (2d6) fire damage.
  • Burning Breath (recharge 5–6). An obsidian minotaur expels a cloud of superheated gas that fills a 10-foot cube adjacent to it. The gas fades after the end of the minotaur’s next turn. Creatures who enter the area or start their turn there must make a DC 16 Constitution saving throw. On a failed saving throw, the target takes 31 (9d6) fire damage and is poisoned for one minute. On a successful saving throw, the target takes half the damage and is not poisoned.
