Demonic Bloodline

Your magic is drawn from the darkness of the Abyss and its Demonic residents. Often results of pacts with Demons or when a Demon mingles with mortal kind, Demonic bloodlines grant incredible power yet the innate cruelty and evil of these powers often result in Demonic Sorcerers to be hunted by inquisitors and other religious figures. That isn't to say that all Sorcerers with this bloodline are evil, yet their power is drawn from an undeniably dark source and its up to the Sorcerer whether they want to give into their power or fight to control it.  

Demonic Magic

Your connection to the Abyssal Plane and its Demons has granted you access to magic normal drawn upon by Warlocks. When your Spellcasting feature allows you to learn a Sorcerer cantrip or Sorcerer spell of 1st level or higher, you can choose the new spell to be from the Warlock spell list or the Sorcerer spell list. You must otherwise obey all the restrictions for selecting the spell, and it becomes a sorcerer spell for you. 

You can speak, read, and write Abyssal. Additionally, whenever you make a Charisma check when interacting with Fiends, you have advantage on the check. 

Demonic Resilience

As your dark magic flows through your body, you start to take on the physical traits of demons. At 1st level, your hit point maximum increases by 1 and increases by 1 again whenever you gain a level in this class.

Additionally, your body adjusts to the harsh conditions of the Abyss as you become resistant to Poison and immune to the Poisoned Condition. 

Demonic Affinity

Starting at 6th level, when you or an ally within 30 feet of you reduce a hostile creature to 0 hit points, you gain temporary hit points equal to your Charisma modifier + your sorcerer level (minimum of 1). At the same time, you can expend 1 sorcery point to instead heal the same amount instead of gaining temporary hit points, any excess healing is lost. 

 

Demonic Wings

At 14th level, you gain the ability to sprout a pair of bat-like demonic 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'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.

Demonic Revelation

At 18th level, you can reveal the true power of your demonic heritage, often to terrifying effect. As a bonus action, you can spend 5 sorcery points to magically transform your body for 1 minute. Gaining all the benefits listed below, which last until the transformation ends: 

• You become resistant to Fire, Cold and Lightning damage. 
• You can see any invisible creature within 60 feet of you, provided it isn't behind total cover. 
• You regain hit points equal to your Charisma modifier at the beginning of your turn. 
• You gain the ability to teleport to any unoccupied space within 60 feet you can see once per turn as a bonus action.
