Fiendish Soul

Your power originates from a distant or recent ancestor that had some sort of fiendish power. Wether your father was a demon, your grandmother was a devil, or even if another distant ancestor was a warlock of the fiend, you have inherited some of that magical power

Fiendish Spells

Starting at 1st level, you learn additional spells when you reach certain levels in this class, as shown in the fiendish spells table. Each of these spells count as sorcerer spells for you, but don’t count against the number of spells you know. 

Whenever you gain a level in this class, you can replace a spell you gained from this feature with another spell of the same level. The new spell must be a sorcerer, warlock, or wizard spell of either the evocation or illusion schools of magic.

1st level	Arms of Hadar, Hellish Rebuke
3rd level	Crown of Madness, Scorching Ray
5th level	Fireball, Hunger of Hadar
7th level	Ice Storm, Evard’s Black Tentacles
9th level	Cone of Cold, Cloudkill

Fiendish Resilience

Starting at 1st level, whenever you cast a spell of 1st level or higher, you gain a bonus to your AC equal to the spell’s level. Until the start of your next turn, or until the spell ends, whichever is longer.

Fiendish Charm

Starting at 1st level, you speak, read, write, and understand either infernal or abyssal. Infernal for devils, and abyssal for demons. Whenever you make a charisma check when interacting with a devil or demon (Depending on which language you choose) your proficiency bonus is doubled if it applies to the check.

 

Fiendish Resistance

Starting at 6th level, you can, as an bonus action, you can expend 1 sorcery point to give yourself resistance to either fire or poison damage (your choice each time you use this feature) for a number of hours equal to your proficiency bonus or until you use this feature again.

Fiendish Wings

Starting at 14th level, you can, as a bonus action you can summon spectral bat wings. While these wings are active you gain a flying speed of 30 feet. The wings last until you use a bonus action to dismiss them, you are incapacitated, or you die.

Fiendish Command

Starting at 18th level, the summon fiend spell is added to the spells you know, and it counts as a sorcerer spell for you. You can cast the spell normally or you can expend 5 sorcery points to cast summon fiend at the 6th level. If you cast the spell in this way, it doesn’t require concentration, but the spell only lasts 1 minute. You can cast this at higher levels by expending a sorcery point for each level above 6th.
