>>38758465Gas type was a thing in that Pokemon Brown rom hack. It was weak to Fire but also super effective against it.
I think the reasoning went something like certain gasses are flammable while others or not so the gas type could be both deal super effective hits to fire and take them from fire.
That was alright, but the real weird thing was that it was x3 weakness instead of a x2. That made no sense. I would keep the dynamic but drop the odd multiplier and probably make steel and grass resist it because steel resists everything and grass types don't need to breathe.
