The Wendigo

 Against all odds, you have managed to commune with a wendigo. Unfortunately for you, however, it seems quite intent on indoctrinating you into its way of life, lending part of its power to you in exchange for... well, you're not quite sure.

Taste of Flesh

Starting at 1st level, when you damage a creature for the first time in a combat, you may deal an addiitional 2d10 + your Charisma modifer necrotic damage to the total damage dealt. They must then make a Wisdom saving throw against your spell save DC or be frightened until the end of their next turn.

Spiritual Shroud

Starting at 6th level, you can call on your patron to enhance your natural prowess in stalking and frightening prey. When you make a check of any kind to stay hidden from an unsuspecting victim, you roll with advantage. Additionally, when you deal damage for the first time using the Cannibal's Bite feature, you receive the damage dealt as temporary hit points that last for an hour.

Cadaverous Determination

Starting at 10th level, you gain resistance to necrotic damage. As well as that, you can choose one damage type when you finish a long rest from cold, poison and thunder. You gain resistance to that damage type until you choose a different one with this feature. Damage from magical weapons or silver weapons ignores these resistances.

Devouring Assault

Starting at 14th level, when you bloody a creature, you can use this feature to brutally attempt to devour them while they're still alive.

Once you use this feature a number of times equal to your Charisma modifier, you can’t use it again until you finish a long rest.
