Fiendish Legacy

Your great magical power comes from your demonic heritage, this energy leads you to an evil nature.
This inheritance can come in many ways. By birth, by the consumption of the flesh of a demon, by the exorcisation of a demon whose essence has left traces in the body and mind of the person,...

Initiated to Hell

From 1st level onwards, your half fiend nature allows you to manifest infernal powers. You learn additional spells when you reach certain levels in this class as indicated on the Fiendish spells Table. The spells counts as a sorcerer spell for you, but it does not count towards the number of sorcerer spells you know. These spells cannot be replaced when you gain a level in that class.

Fiendish Spells

You can speak, read, and write Infernal. Additionally, whenever you make a Charisma check when interacting with fiends, your proficiency bonus is doubled if it applies to the check.

Tough Devil

As fiendish blood courses through you, it makes you harder to kill than most and more durable. You have resistance to poison damage and have advantage on saving throws against being Poisoned.

Also, your skin leather is stronger than a normal one. When you aren’t wearing armor, your AC equals 13 + your Dexterity modifier.

Infernal affinity

Starting at 6th level, when you cast a spell, you can spend 3 sorcery point to gain resistance to the type of damage dealt and you can add your Charisma modifier to a damage roll for that spell.
Also, you can spend 1 sorcery point to turn your resistance to poison into an immunity for 1 hour

Hell spawn

At 14th level, you gain the ability to sprout a pair of wings and tail from your back, gaining a flying speed equal to your current speed. You can create these as a bonus action on your turn. They last until you dismiss them as a bonus action on your turn.

You can’t manifest these 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.

You can make the wings appear without necessarily making the tail appear and vice versa, however making one grow after having made the other will cost an extra bonus action.

In addition, you can grab a creature with your tail or inflict 2d6 bludgeoning damage + your strength modifier.

Heir of Hell

You can spend 15 sorcery points to summon a pit fiend that can be lawful to you.

You must be of evil alignment for the demon to obey you, if you are not, it will attack you and you must kill it in order to demonstrate your power, once you defeat it, the next [monster]pit [fiend/monster] you summon will not attack you, but will not be loyal to you and wont try help you if you're in deadly situation.

However if you are evil, it will obey you, but have 10% to turn against you or if you show any sign of alignement other than evil, you will have to defeat it in order to confirm your power and cruelty, the next pit fiend will obey you like the first and so on.
