The Glutenous One

You make a pact with a demon from deep in the Abyss. It wishes to consume all and requires you to travel the world and feed in exchange for its dark powers. 

Expanded Spell List

The Fiend lets you choose from an expanded list of spells when you learn a warlock spell. The following spells are added to the warlock spell list for you.

Fiend Expanded Spells

Spell Level	Spells
1st	absorb elements, goodberry
2nd	magic mouth, protection from poison
3rd	fireball, hunger of hadar
4th	Leomund's secret chest, summon greater demon
5th	Banishing smite, enervation

Abyssal Physique

Starting at 1st level, when you regain health (either by short rest, long rest, or healing magic) you can add your Charisma modifier (minimum of 1) to the HP healed.

Arcane Consumption

Starting at 6th level, you offer arcane magics to your patron in exchange for more power. Once per short rest, when you successfully counterspell any spell, the counterspell cast does not consume a spell slot. 

Abhorrent Meal

Starting at 10th level, you can consume the flesh of a creature. Until you finish a long rest, you have resistance to all damage from weapon and spell attacks from that type of creature. For example, if you eat goblin flesh, you gain resistance to all weapon and spell attack damage from all goblins until you finish a long rest (goblinoids do not count). 

Serve the Master

Starting at 14th level, when you hit a creature with an attack, you can use this feature to instantly transport the target to your patron's lair. The creature disappears and reappears on your patron's dinner table to be consumed.

At the end of your next turn, the target returns to the space it previously occupied, or the nearest unoccupied space. If the target is not a fiend, it takes 10d10 force damage from your master's attempts to eat the creature.

Once you use this feature, you can’t use it again until you finish a long rest.
