All right, say you have Fire, Light, Magma (Not really related to Fire at all in actual science, but it seems to be a lot in fiction), and then this Hellfire, if that gets in. Then you add Solar, that would be three-Fire like substances, not counting Magma. It would be a bit redundant forthat many Fire-objects, even if it's just firery lasers.
