Charge. If the construct 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.

Undead Fortitude. If damage reduces the construct to 0 hit points, it must make a Constitution saving throw with a DC of 5 + the damage taken, unless the damage is radiant or from a critical hit. On a success, the construct drops to 1 hit point instead.

Magic Resistance. The construct has advantage on saving throws against spells and other magical effects.

Multiattack. The construct may attack twice in a turn. Once with its battleaxe and once with either its bite or petrifying gaze.

Battleaxe. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 9 (1d8 + 4) slashing damage plus 4 (1d8) poison damage.

Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 11 (2d6 + 4) piercing damage plus 10 (3d6) poison damage.

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

Petrifying Gaze. (Recharge 5-6) The construct can force one creature within 30 feet to make a DC 14 Constitution saving throw if the construct isn't incapacitated. On a failed save, the creature magically begins to turn to stone and is restrained. It must repeat the saving throw at the end of its next turn. On a success, the effect ends. On a failure, the creature is petrified until freed by the greater restoration spell or other magic.

A creature that isn't surprised can avert its eyes to avoid the saving throw at the start of its turn. If it does so, it can't see the construct until the start of its next turn, when it can avert its eyes again.

If it looks at the construct in the meantime, it must immediately make the save.
