Fire Dragon's Roar

Fire Dragon's Roar (火竜の咆哮 Karyū no Hōkō) is a Fire Dragon Slayer Magic Spell.

Description
The Dragon's Roar exclusive to the Fire Dragon Slayer. The user first inhales, gathering fire in his/her mouth, and then releases such fire in the direction of their opponent, creating a large, exploding fireball which damages and burns his/her foes. This spell can apparently be performed in two ways: the first and most "complicated" one involves the user putting his/her hands before his/her mouth in a pose resembling that of a trumpeter before releasing his/her fire, prompting it to be expelled between his/her fingers. The flames produced by this version start out as a very thin line, enough to be fit between the user's fingers, before suddenly enlarging to strike the opponents. The other, simpler and seemingly faster way simply has the user gather flames and then shoot them out, with no seeming stance required, and a much larger beam of fire being produced directly from the user's mouth.
