Infernal Sorcery (5e)

Your bloodline is infused with the influence of a powerful infernal. Whether through a demonic pact, the corruption of one of your ancestors, a curse or a boon, this taint is the source of your innate magical talents. Most inheritors of such a bloodline would typically choose to hide the dark influence in their blood, though there are some who take pride in their bloodlines, using their powers to the most of their potential.

## Dark Heritage

You gain access to the Dark Metamorphosis spell. You can speak, read, and write Infernal. Additionally, you know the Thaumaturgy cantrip which doesn't count against your number of sorcerer spells known.

Level 1 Transmutation
Casting Time: 1 action
Range: Self
Components: S, M (The blood of an Infernal Sorcerer)
Duration: 1 hour
As an action, you may spend a spell slot to transform into a monstrous demon form. When entering this state, your creature type becomes fiend, you become resistant to one damage type of your choice (excluding radiant damage), and you may cast the Thaumaturgy cantrip as a bonus action. As a bonus action, you may end the spell early, reverting to your natural state.
In addition, you may choose one of the following features.
* You grow one size category
* You add your Charisma bonus to your Strength checks and Strength saving throws.
* You gain a magical natural weapon that deals 2d6 necrotic damage. You use your Charisma for your attack and damage rolls using this attack. On a successful hit, you gain your dealt damage in temporary HP
* You gain 60 ft of darkvision. Magical darkness doesn't impede this feature.

At higher levels: When you cast this spell using a spell slot of 2nd level or higher, the amount of features you gain increases by 1 for each level above 1st

## Infernal Resilience

The dark magic flowing through your veins renders your body resilient to harm. At 1st level, your hit point maximum increases by 1 and increases by 1 again whenever you gain a level in this class.

Additionally, when you aren't wearing armor, your AC equals 13 + your Dexterity modifier.

## Demonic Adaptation

Starting at 6th level, you are able to manifest additional demonic features by pushing your Dark Metamorphosis even further. When casting Dark Metamorphosis at a 3rd level or higher, you may choose to also gain one of the following features on top of the spell’s normal features

* As a reaction, you may spend a sorcery point to change your current damage resistance.
* Your tail becomes a magical natural weapon that deals 2d6 necrotic damage. This weapon has a reach of 10 ft. You use your Charisma for your attack and damage rolls using this attack. As a part of the same action, you may use this weapon immediately after making another melee attack. On a successful hit you gain a temporary hp equal to the damage dealt as long as you have not gained temporary health during the turn you used this attack.
* You gain immunity to Fire damage
* You gain immunity to Poison damage and the Poisoned condition
* You sprout wings and gain a 30 ft fly speed

## Infernal Talent

At 14th level, you choose one of the following spells: Dominate Person, Flame Strike, or Hold Monster. You learn the spell, and you can cast it without components. Each spell counts as a sorcerer spell for you, but it doesn’t count against the number of sorcerer spells you know.

After casting Dark Metamorphosis at 5th level or higher, you may cast your chosen spell once without expending a spell slot at the same level that Dark Metamorphosis was cast.

## Fearful Presence

At 18th level, your demonic form radiates a terrifying presence which shakes your foes’ resolve. While using Dark Metamorphosis, any creature hostile to you that starts its turn within 20 feet of you must make a Wisdom saving throw against your spell save dc. On a failed save, the creature is frightened until the start of its next turn. If a creature's saving throw is successful, the creature is immune to your Fearful Presence for the next 24 hours.

In addition, you may now cast Dark Metamorphosis at 1st level without spending a spell slot.
