Crystalline Minotaur

Charge. If the 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 14 Strength saving throw or be pushed up to 10 feet away and knocked prone.

Labyrinthine Recall. The minotaur can perfectly recall any path it has traveled.

Not so Reckless. At the start of its turn, the minotaur can gain advantage on all melee weapon attack rolls it makes during that turn.

Multiattack. The Crystalline Minotaur makes two attacks one with it's greataxe and one gore attack.

Greataxe. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 17 (2d12 + 4) slashing damage.

Gore. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) piercing damage.

Bonus Action:

Crystal Shard. Ranged Weapon Attack: +6 to hit, range 80/320 ft., one target. Hit: 2 (1d4) piercing damage.

Reflect once during a combat the Crystalline Minotaur may use it's reflective surface to redirect a spell that targets the Minotaur. The new target must be within 10 feet of the Minotaur.

After making an attack may move up to its speed, this movement does not provoke at attack of opportunity.

Villain Actions are action that are taken once per round in the order.

Round 1: All attacks in the first round of combat against the Crystalline Minotaur are at disadvantage.

Round 2: Cast Maze on one target within 30 feet of the Crystalline Minotaur.

Round 3: The image of one enemy within 10 feet of the Crystalline Minotaur appears on all the Crystalline surfaces of the Minotaur. The Crystalline Minotaur and the target each take half of all the damage dealt to the Minotaur.

Round 4?: When the Crystalline Minotaur is close to dying it begins radiating energy from within it's body. (This is a warning for the players). When the Minotaur dies it explodes into thousands of crystalline shards. Every creature within 15 feet of the Minotaur makes a Dex save DC 14. On a failed save the creature takes 4d6 piercing damage and half as much on a successful save.
