The Eternal Flame

You are blessed with the element of fire. However you received that may differ; perhaps you are a fire genasi with a stronger connection to your bloodline than others, or maybe you were born through a cataclysm. You could be struck with power after a near-death experience with fire, or maybe have been in contact with the primeval phoenixes, earning their favor to light the world aflame.

No matter your lineage, fire runs through every aspect of you, waiting to burst. You may see this as a curse, or a blessing, but even the strongest minds with this power have the innate elemental urge to consume all in flame, whether for good or evil. Warm the hearts of the cold and forgotten like a mother's embrace, or reduce this world to sinless ash. 

Such power may reflect on a person depending on how they received it. One born with the power of the elemental planes could have bright red-orange blood like magma, or eyes like molten metal. One blessed by a phoenix may have feathers appear on their skin, or if blessed by an Efreet, hands of brass.

Those with the power of flame must be careful who they reveal it to, and learn to control where their powers manifest. Many of mortalkind look at fire with fear and fascination, and those who control it are even more judged. A sorcerer of the flame may be outcasted from their home due to the affinity, being blamed for every fire that is conjured nearby, while others may be worshipped like gods in a cult-like manner. But nonetheless, like fire, it is up to the wielder on how they harness such a view.

Ember Soul

When you choose this Sorcerous Origin at 1st level, you gain the Produce Flame cantrip. This counts as a sorcerer cantrip for you, and does not count against the number of cantrips you know.

In addition, you automatically learn additional spells when you reach certain levels in this class, as shown on the Inferno Spells table. Each of these spells counts as a sorcerer spell for you, but it doesn't count against the number of sorcerer spells you know.

Whenever you gain a sorcerer level, you can replace one spell you gained from this feature with another spell of the same level. The new spell must be a conjuration or evocation spell from the sorcerer, warlock, or wizard spell list.

Empowered Flames

The flames that fuel your power can be utilized in almost otherworldly ways, and you have learned some tricks to bind yourself to them. At 1st level in this class, whenever you roll fire damage on your turn, the roll gains a bonus to equal to your Charisma modifier. In addition, when you expend a spell slot to cast a spell that includes a fire damage roll, you regain hit points equal to the slot's level + your Charisma modifier.

All to Ashes

You know how to convert raw magic energy into flame without tapping into your reserved power to a natural level. Beginning at 6th level, when you cast a spell that deals acid, cold, lightning, poison, or thunder damage, you may convert that damage type to fire, as per Transmuted Spell, without using any sorcery points.

Profane Fire

Your flames come from the primordial fires, searing even the most resilient as they are empowered with pure, fiery energy akin to the sun. At 14th level, any spells and effects you create treat immunity to fire damage as resistance. When a creature's fire immunity is bypassed into resistance using this feature, any ability to bypass resistance (such as the Elemental Adept feat, or the Elemental Bane spell) also applies.

 

Living Blaze

You have achieved the height of your potential, becoming one with all flames. At 18th level, you gain immunity to fire damage, and are immune to nonmagical aging, for as long as you take care of your mortal form.

In addition, when you are subjected to fire damage, as a reaction, you may ignore the damage and instead heal for the amount dealt. You can use this reaction up to your proficiency bonus times daily, and regain all uses at the end of a long rest.
