Horned Devil

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

Devilish Resilience. The devil is resistant to cold damage and to bludgeoning, piercing, and slashing damage from nonmagical attacks. In addition, it is immune to fire damage and poison damage and to the poisoned condition.

Magic Resistance. The devil has advantage on saves against spells and other magical effects.

Multiattack. The devil makes two Fork attacks and one Tail attack, or it makes three Hurl Flame attacks.

Fork. _Melee Weapon Attack:_ +10 to hit, reach 10 ft., one target. _Hit:_ 19 (3d8+6) piercing damage.

Tail. _Melee Weapon Attack:_ +10 to hit, reach 10 ft., one target. _Hit:_ 22 (3d10+6) piercing damage. If the target is a creature other than a Construct or Undead, it must succeed on a DC 17 CON save or lose 10 (3d6) HP at the start of each of its turns due to an infernal wound. Each time the devil hits the wounded target with this attack, the damage dealt by the wound increases by 10 (3d6). Any creature can take an action to stanch the wound with a successful DC 12 WIS (Medicine) check. The wound also closes if the target receives magical healing.

Hurl Flame. _Ranged Spell Attack:_ +7 to hit, range 150 ft., one target. _Hit:_ 20 (5d6+3) fire damage. If the target is a flammable object that isn't being worn or carried, it also catches fire.

Headbutt. The horned devil slams its horned head into a creature it can see within 5 feet of it. The target must make a DC 17 STR save. On a failure, the target takes 7 (2d6) bludgeoning damage and is knocked prone. On a success, the target takes half the damage and isn't knocked prone.
