Baron of Hell

 Charge. If the baron moves at least 15 feet straight toward a target and then hits it with a gore attack on the same turn, the target takes an extra 38 (7d10) piercing damage. If the target is a creature, it must succeed on a DC 21 Strength saving throw or be pushed up to 20 feet away and knocked prone.

Devil's Sight. Magical darkness doesn't impede the devil's darkvision.
