Volcanic Eruption

.

Seismic Disruption

Your connection to the seismic event that occurred concurrently to your birth has given you some level of power over flame. The more you use this power, the harder it is to control. Many people live with these powers but suppress them for decades at a time. One ability shared by all volcanic sorcerers is the ability to create flame. Upon touching an object, you may attempt to set it on fire by your own will. Roll a d20, on a roll of 15 or higher, the object is set aflame and burns as much as physics allow for it to.

 

Also at the 1st level, you can emit a flaming aura as a bonus action, which has one of eight effects. You are able to do this a number of times equal to your charisma modifier per long rest.

d8 roll	Effect of aura
1	Your eyes fill with flame, granting you a +5 to intimidation checks for one minute.
2	Your hands emit a glow, creating a 30foot radius of bright light for one minute.
3	You emit an angelic glow, making intelligent creatures slightly more friendly to you.
4	You hover off of the ground, and can move 30feet through the air in addition to your normal movement for 1d6 turns. You as a character are not aware of when it ends.
5	The ground around you heats up, becoming more akin to hot coals than whatever it was before. These coals do not start fires or harm those who walk on them, but are difficult terrain for 3 turns.
6	Your fists glow and your unarmed strikes with your hands deal 1d8 fire damage for 1d6 turns.
7	Gas rises through your throat and you emit a foul, wretched belch that deals 2d4 necrotic damage and 2d6 fire damage to creatures in a 10 foot line (you have just enough time to turn and aim). Creatures in the line make a DC 15 dexterity saving throw.
8	Creatures within 5 feet of you take fire damage equal to your sorcerer level for 3 turns or until they move.

 

Flare of Chastisement

At the 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, wild, uncontrollable flares erupt from you. These flares cause creatures in a 15 foot cone in a direction determined via d8 to take fire damage equal to half of your sorcerer level.

 

Also at the 6th level, you also gain a small amount of additional control over your flames. You have advantage on rolls to set objects aflame at will, and can also produce floating flames that provide light and warmth to you and your allies, which are fueled by the air around them. 

Burning Rage

 

At the 14th level, when you are hit by a melee attack, you punish your foes and reap the benefits. You can use your reaction to expend a spell slot, or sorcery points equivalent to a slot, and heal a number of hitpoints equal to your charisma modifier plus the slot level. In turn, the foe who hit you takes fire damage equal to your sorcerer level. 

Immeasurable Heat

Beginning at the 18th level, you gain immunity to fire damage. You are able to grant resistance to fire damage to a number of allies equal to you charisma modifier for one minute, once per long rest. In addition, fire damage dealt by your spells/class features ignores resistance.
