Fire that burns body, soul, and abstraction alike. Immolate, incinerate, and consume what fire shouldn't be able to touch: hellfire can burn a memory, a spell, or the strength of a soul as readily as flesh.
a flaming meteor crashes on your enemies, then animates as an infernal.
Feats
Name TBD: When you inflict two consecutive instances of hellfire damage on the same target, you gain 1 soul shard.
Precision Flames: When you cast Conflagrate, you can choose to have the fire spread only to targets of your choice within the area, rather than all targets.
Notes
Soul Burn should be a feat
Further ideas: circle of flames, hellfire storm, etc.
