The Black Flame Element is a mixture of Elemental Effects which can be utilized offensively by both hunters and the monster, Fatalis. It uses the intense heat of flames alongside an unknown but powerful energy to cause additional damage. The difference in elemental power is rather large however, Fire only dealing 50% of its full power whereas Dragon deals 150%. The Black Flame Element is currently exclusive to the Frontier Series and was introduced at Monster Hunter Frontier G3. Fatalis are the only monsters capable of using the Black Flame Element.
The Black Flame Element can be infused into weapons to cause additional elemental damage. When a black flame weapon strikes, it will apply both elemental values at once, but will either release a burst of flame or a burst of black and red energy into the wound, the effect shown will be the one which is most effective on that part of the monster. Black Flame Element can be extremely effective against certain monsters.
