Well technically they only said you want a movement skill to get past the gaps, they could have enemies on the other side you can bodyswap to. But yeah that sounds clunky as shit, also wouldn't work well with console controls I'd assume, so it's probably going to be similar to mirror arrow where it creates a body then swap with it. Wand/staff based maybe. They could just unfuck flame dash and not have to add more skills though. Like I still don't get why flame dash needs charges when shield charge and whirling blades can just be spammed without any issues. Sure it goes through shit, but it's also shit range, just nerf the damage on it/make it only do instant fire damage on pass through so it doesn't leave billions of laggy trails of fire and everyone can just use that instead.
