I was referring more to the part where you said: "it may occure without any temperature changes involved if the power forbids that. Though most of the time, heat acts as a cataclyst, so if it happens, it should progress slowly." where I'm assuming you meant rusting by 'it'. Sounded like it will happen, just not quick enough.

I kind of forgot heat tends to be a catalyst though, so I'll have to think over. Well, I guess that means if one has the power to maintain a constant temperature they will virtually be immune to both ice-based elemental powers and fire-based elemental powers, huh.
