Wendigo

A creature that starts its turn within 10 feet of the wendigo must succeed on a DC 15 Constitution saving throw or be paralyzed by gnawing cold and crippling hunger for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the wendigo's Aura of Starvation for the next 24 hours.

The wendigo has advantage on saving throws against spells and other magical effects.

The wendigo makes three attacks. two with its icy claw and one with its bite. Alternatively, it uses its Frozen Spittle twice.
