Wendigo

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

Regeneration. The Wendigo regains 20 hit points at the start of its turn if it has at least 1 hit point remaining.

Savage Hunger. When the Wendigo hits with a melee attack, it regains hit points equal to the damage dealt.

 Multiattack. The Wendigo makes three attacks: one with his Bite and two with his Claws.

Bite. Melee Weapon Attack: +12 to hit, reach 5 ft., one target. Hit: 19 (3d8 + 6) piercing damage plus 10 (3d6) cold damage.

Claws. Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 18 (3d6 + 6) slashing damage.

Devour. (Recharge 5-6): The Wendigo begins to shapeshift its maw and open its mouth. Unless 50 damage is done before its next turn, the Wendigo targets a restrained or incapacitated creature within 5 feet. The target must succeed on a DC 20 Constitution saving throw or take 54 (12d8) necrotic damage. If this damage reduces the target to 0 hit points, the Wendigo regains hit points equal to the target’s maximum hit points.

Savage Attack. The Wendigo can make a Claw attack as a bonus action if he has taken damage this turn

The Wendigo can take 2 legendary actions, choosing from the options below. Only one legendary action option can be used at a time, and it can be used at the end of another creature's turn. The Wendigo regains spent legendary actions at the start of his turn.

• Howl of Despair. (Cost 2 Actions): The Wendigo emits a terrifying howl. Each creature within 30 feet that can hear it must succeed on a DC 18 Wisdom saving throw or be frightened for 1 minute. A frightened creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

• Savage Swipe. The Wendigo makes a Claw attack against a target within reach. If the attack hits, the target must succeed on a DC 18 Strength saving throw or be knocked prone.

• Blood Frenzy. The Wendigo moves up to his speed towards a creature that has less than half of its hit points remaining and makes a Claw attack against it.
