The blood flows

From 1st level, you gain ability to use the blood of resently killed enemies within 60 ft. of you to cast spells without usage of spell slot as free action. You can do this 2 times until long rest. You can cast spells only on spellslot level, that is available to you. You can't use this feature for a spell with spellslot higher than 5.

Also, from 2nd level you can use your own blood to generate sorcery points, as a bonus action you can decrease you maximum amount of hp, and gain 1 sorcery point per 2 hp. You can't reduce your hp more than half of you hp total. Your HP maximum will return to normal after a long rest.

Abyssal summoning

Starting at 5th Level you learn the "Summon lesser demons" spell, which doesn't count against the total number of spells learnt. Demons summoned that way won't be agressive towards you and will obey all spoken commands, because they see you as superior fiend. Adittionaly you can summon demons of CR 1 higher, than it is written in the spell's description.

Starting at 7th Level you learn the "Summon greater demon" spell which doesn't count against the total number of spells learnt. The summoned demon will not try to break free of your control and will obey all spoken commands for the half of the spell duration, because they see you as superior fiend. After 30 minutes it will see your not fiendish aura and try to break free, as per spell description. Adittionaly you can summon demons of CR 3 higher, than your spell level, instead of 1.

Starting at 9th Level you learn the "Planar binding" spell which doesn't count against the total number of spells learnt. This spell does not require material components if you cast it on a fiend type creature.

Starting at 18th Level any summoned demon obeys you for full duration. Also you can use twinned spell for the Summon Greater Demon spell.

Upon the abyssal wings

At 14th level, you gain the ability to sprout a pair of fiendish wings from your back, gaining a flying speed equal to your current speed. You can create these wings as a bonus action on your turn. They last until you dismiss them as a bonus action on your turn. You can choose their appearance only once, when you use this ability for the first time.

You can't manifest your wings while wearing armor unless the armor is made to accommodate them, and clothing not made to accommodate your wings might be destroyed when you manifest them.

Abyss made manifest

At 18th level, when you die in any plane other than the abyss your body disintegrates into ashes and you re-spawn in the abyss along with all your equipment.

Your body now rejects the touch of healing of divine magic, healing spells now damage you and regular resurrection spells have no effect on you, instead fire heals you by the total damage amount. For the purposes of all spells and abilities you become a fiend. If you die on the plane of abyss, you can be resurrected with true ressurection or wish.

Your hit point maximum increases by 3 for each level in this class.

You gain Immunity to non-magical piercing, bludgeoning, slashing; fire damage, poisoned, restrained, charmed and frightened condition. And advantage on saving throws against magic.

You now have a demonic true name, if someone issues a command to you using your true name, you can resist it as per Summon Greater Demon spell.
