Heart of Fire

Forged through Fire and flames or a spark ignited through mystical means. You or someone of your lineage was exposed to the primal fire or a mystical breath of fire from a phoenix. Sorcerers who awaken their Heart of Fire tend to be passionate and a bit reckless. There have been cases where those who awaken, fail to control their inner fire and perishes from burning themselves up. They often have parts of their body glow like tinder or manifest flames around them. Whatever the case may be, you are now empowered/bound to take care of the fire in your heart from melting you.

Tempered Hearthstone

When you reach 6th level, your body has slowly adapted and improved its durability and efficiency in handling the raw power circulating through you. You gain resistance to fire damage.

Whenever you deal fire damage, you may as a free action expend Origin Hearth charges. For every 25 charges expended this way, you may deal an additional 2d8 fire damage to the next attack or instance of damage from a damage dealing spell you cast until the end of your next turn. Spells that hit multiple times can only empower the first damage instance unless they choose to expend charges to empower individual damage instances at the time of casting.

Ex.
3rd Level Fireball + 25 charges = 8d6[Fire] + 2d8[Fire] for each target affected.
2nd Level Scorching Ray + 25 Charges = 2d6[Fire] + 2d8[Fire] for 1 ray, 2d6[Fire] for other 2 rays.
2nd Level Scorching Ray + 50 Charges = 2d6[Fire] + 4d8[Fire] for 1 ray, 2d6[Fire] for other 2 rays.
2nd Level Scorching Ray + 50 Charges = 2d6[Fire] + 2d8[Fire] for 2 rays, 2d6[Fire] for the last ray.
