Hellspawn (Reworked)

Your Soul has somehow been influenced by a creature from the Nine Hells causing you to develop a variety of demonlike powers such as granting you the ability to temporarily transform into a demonic being and allowing you to experience the sinister spellcasting abilities of the Fiends. Have cultilsts tried to offer you as a sacrifice to a certain Archdevil or have u struck a deal with one of them yourselves? Regardless of they way you came into contact with the Nine Hells you now begin to slowly turn into a Fiend yourself. Are u going to try and stop this from happening or are you willing to undergo the transformation for the powers that will be granted to you in exchange? 

Abyssal Magic

You learn certain additional spells at the sorcerer levels noted in the Abyssal Spells table. They count as sorcerer spells for you, but they don't count against the number of spells you know. Whenever you gain a level, you can replace one spell from this feature with another conjuration or evocation spell of the same level from the sorcerer, warlock, or wizard spell list.

Demonic Form

When you choose this origin at 1st level, you gain the ability to undergo a transformation, unleashing the demonic power within you. As a bonus action, you can take on a demonic form. While in this form, you retain your game statistics, but your body becomes demonic in appearance. While in your demonic form you gain the following benefits:

• Your hands become natural weapons that deal 1d6 slashing damage on hit, and you use your Charisma, in place of Strength, for the attack and damage rolls. When you reach 6th level in this subclass the damage die becomes a d8.
•  If you are not wearing armor, you gain a bonus to your AC equal to your Charisma modifier (minimum of 1)
• As a bonus action, you can grant yourself temporary hit points equal to your Charisma modifier (minimum of 1).
• During the transformation you gain resistance to both cold and fire damage.

 You also gain the Infernal Language.

 

This form lasts for 1 minute, unless you are incapacitated, or you end it as a bonus action. You can transform a number of times equal to your Charisma modifier (minimum of once), and regain all expended uses when you finish a long rest.

You also gain the Infernal Language.

Extra Attack

Starting at 6th level, you can attack twice, instead of once, when you take the Attack action. Moreover, you can cast one of your sorcerer cantrips in place of one of those attacks.

Infernal Transfiguration

As demonic powers start to integrate into your body, it causes physical traits of a creature from the Nine Hells to emerge, making you more durable and allowing your Hellspawn Claws to slice through regular armaments.
At 6st level when you get this feature, your hit point maximum increases by 6 and increases by 1 again whenever you gain a level in this class. Additionally your natural weapon attacks while in your demonic form count as magical for the purposes of overcoming resistances and immunity.

Fiendish Resistance

Beginning at 14th level, your hellish power can shield you from harm. As a reaction, when you take damage while in your demonic form, you can expend spell slots to reduce the incoming damage. For each level of the spell slot you expend as part of the reaction, reduce the incoming damage by 1d10.

Nine Hells Unchained

However you aquired the power of the Nine Hells, it is now fully fleshed out and presents its full glory, as you have familiarized yourself with it. Starting at 18th level, you can permanently keep up your demonic form as it only ends when you choose to do so. Furthermore you can enter it as a bonus action without of being limited in your access. Also, while in your Demonic Form, you gain the following additional benefits:

• Warp Dimensions: Once per turn, you can grant yourself temporary hitpoints equal to 1d10 + you Charisma Modifier as a free action. Once you have used this feature a number of times equal to your proficiency bonus, you cannot do so until you finish a long rest. If you do so you must not grant yourself temporary hit points as a bonus action as per the Demonic Form feature.
• You are immune to bludgeoning, piercing, and slashing damage from non-magical attacks.
• When you hit a creature with a natural weapon attack it takes an additional 1d8 magical slashing damage. Your Hellspawn Claws gain a reach of 10 feet.
• You gain a flying speed equal to your walking speed
