Hunger

While raging you are overcome by an incredible hunger. This Feature can be used up to [Your Constitution Modifier] times per Long rest.

Humanoid: You gain Temporary Hitpoints equal to a quarter of the creature's max hp, rounded down.
Beast: You heal 1d12 hp.
Dragon: You gain one use of a Breath weapon related to the colour of the target.
Fey: You can cast Misty Step for free once.
Undead: You can't eat this Creature Type.
Abberation: You gain the Aberrant Mind Feature until your next Long rest.
Celestial: Your attacks deal an additional 1d6 radiant damage for 2 Rounds.
Plant: You heal 1d10 hp.
Construct: You can't eat this Creature Type.
Elemental: You can't eat this Creature Type.
Ooze: You can't eat this Creature Type.
Giant: Your Size increases by one until your Rage ends.
Fiend: You gain Fire Resistance for the duration of your Rage.

Starved Mind

While raging you feel so starved that your mind can't be influenced by outside effects anymore, beginning at 6th level, you can’t be charmed or frightened while raging. If you are charmed or frightened when you enter your rage, the effect is suspended for the duration of the rage.

Additionally you are Immune to Psychic damage while Raging.

Call upon Shadows

Beginning at 10th level, you can use your action to call upon the Shadowfell to summon one of three Creatures:

A Salamander, A Xorn or A Water weird. You can command them as your Bonus action, they stay for 5 Rounds and if they don't receive a command they will use the dodge action and end their turn.

While this effect is active all creatures within 1000 ft. are affected by a random Shadowfell Despair without the detrimental effects. (Flavour)

This can be used once per Long rest.

Creature of the Shadows

Starting at 14th level, you are resistant to necrotic damage, and deal 1d6 additional necrotic damage with every attack.

While raging you are immune to necrotic damage and have advantage on Spell saving throws.

Additionally all creatures of the shadowfell act neutral towards you.
