Flame Sorcery

A deep fire has awoken inside you. The soul of a phoenix or a spirit of fire has entered your body, granting you mastery over fire spells. It makes you warmer to the touch and more intimidating to other that seek to do you harm.

Flame Speaker

The arcane magic you command is infused with elemental flame. You can speak, read, and write Infernal. Knowing this language allows you to understand and be understood by those who speak its dialects. You are also more intimidating than before. You have proficiency with Intimidation.

Fiery Intensity

Starting at 1st level, you find that fire becomes protective of you. As long as there is an open flame within 5 feet of you, you have +1 bonus to your AC.

Beacon of Flame

At 6th level, you gain resistance to fire damage. In addition, whenever you start casting a spell of 1st level or higher that deals fire damage, unnatural fire erupts from you. This eruption causes creatures of your choice that you can see within 10 feet of you to take fire damage equal to half your sorcerer level.

Channel Fire

At level 6, you gain the ability to absorb or instill heat into objects or creatures. As a special action you can absorb heat from any object or creature other than yourself that is warmer than tepid, or instill heat into any object or creature that is colder than tepid. If you absorb heat from a source that is boiling or hotter, you can add 1d6 damage to your next fire damage spell. If you instill heat in a living creature that that is hyperthermic or has less than 10 HP remaining, you heal them for 1d6 HP.

At Higher Levels: you increase the fire damage and healing by 1 additional d6 at levels 14 and 18.

Raging Inferno

Starting at 14th level, when you are hit by a melee attack, you can use your reaction to deal fire damage to the attacker. The damage equals your sorcerer level. The attacker must also make a Constitution saving throw against your sorcerer spell save DC. On a failed save, the attacker receives an additional 6 fire damage.

Soul of the Phoenix

At 18th level, you gain immunity to fire damage.

You also gain a magical flying speed of 60 feet. Once per short rest, as an special action, you create a Blazing Phoenix that has the same properties of a Fireball spell at 3rd level  whenever you cast a spell that deals fire damage.

If you wish to use this ability again, you can spend six sorcery points to do so.
