The bottle can then spew out a blade of black flames to use in sword combat, or it can fire balls of the black flames as a long range attack at an opponent. Not surprisingly, it appears to use a large amount of energy. Though said by Ryan himself to burn everything that is touched by the jet-black flames, to the degree of being able to burn an entire forest.
