If you ask me? I have absolutely no idea how MMA applies to a literal [i]mouse[/i].

But yeah, 0Z, i think you'll have to elaborate on the specifics of your character's fire ability: is it exactly how it sounds - just casting flames onto something upon touch? If so, what are the attributes of said flames: size, damage potential, whether they have some fuel to make them last, or do they simply snuff out if they don't contact anything flammable? Stuff like that.

That's all i can suggest without an official judgement from Rilla; keep in mind though that RP fighting requires extensive amount of detail and depth to even work as a competetive enviroment, so your combat posts will end up at at least 5 times the wordcount of your current character sheet bare minimum - if you don't half ass them.
