consume flesh. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 15 (2d10 + 4) piercing damage. the target must mack a constitution saving through (DC 10) or it takes an additional 9 (2d8) necrotic damage and its hit points maximum is reduced by the same amount. the wendigo regains hit points equal to the amount of necrotic damage delt

HUNGERING CURSE. when the wendigo is killed, the closest humanoid within 15 feet of it must succeed on a DC 10 wisdom or become cursed with the wendigo spirit. if there are multiple creatures in range, the DM chooses the target at random. the cursed creature has an irresistible hunger to eat humanoid flesh, specifically for the flesh of its race. while cursed, the creature feels a constant hunger and must succeed on a DC 10 Wisdom saving throw anytime there is a humanoid within eyesight of it, or spend the next turn consuming the flesh of the course. The cursed creature makes this save with disadvantage if the corpse is of the same race. a creature can repeat this save at the end of its subsequent turns. on a success, the creature is immune to the effect of the curse for the next 1 hour, if the creature fails the saving throw four times while cursed it becomes a wendigo. the curse can only be removed by the effects of a spell, such as remove curse, or a poison of light is poured onto its back. once it becomes a wendigo it gets the stats of a wendigo and the only way to return the stats to the original form is to use a wish spell.

STARVING HUNTER. The wendigo has advantage on Wisdom (Perception) checks or intelligence (investigation) checks to find other humanoid creatures
