Hellfire Magic

Hellfire magic, is a discipline of magic that is extremelly difficult for most magic user due to many it's requirement...one needs to have made a contract with an Ignis and also to have a moderate amount of DE within themselves....the Ignis needs to be pure.Spellcasters would often spend years training in the arts of the Fire, just to even be able to reach the basics of Hellfire.But if one would manage to control the power of this dark art, he would be able to control any fire magic with ease.

There is a difference between normal Fire and Hellfire:

The normal Fire leaves marks on the body, that can be healed....But Hellfire, that's a different story....The place were someone is touched by Hellfire will not burn physically.That place will feel like it's constantly being burned.No one besides another Hellfire user would be able to remove that.
