Shield of Flame

At 6th level you draw on the flames of your patron to rebuke those who harm you and protect from future attacks.

You may use you reaction when hit with a melee spell or attack to shroud yourself in flame for 1 minute dealing half of the triggering damage in fire damage back to the creature that hit you.

Until the end of the duration whenever you cast a fire based spell or cantrip you gain temporary hit points equal to your warlock level + your charisma modifier.

Once you use this feature you cannot use it again until you finish a short or long rest.

Intense Flames

You are immune to fire.

Additionally any spell or cantrip you cast that deals fire damage overcomes immunity and resistances, causing an immune creature to become resistant and a resistant creature to take full damage.

Fiery Consumption

You reach your hand out and point at a creature in 150 ft of you. The target makes a dexterity saving throw or takes 8d8 fire damage on a failed save or half as much on a successful one.

On a failed save the target is burning for 1 minute shedding bright light for 30 ft and taking 4d8 fire damage each turn. The target may remake the save each round at the end of it's turn.

The flames ignite anything flammable not worn or carried. It cannot be extinguished  by nonmagical means.

Any creature killed by this ability is reduced to ask along with anything nonmagical worn or carried.

You can use this feature once per long rest.
