During the puzzle section of the guard bribe area, it is possible to wedge yourself in between two of the moving rocks w/ a very precise trick. Basically, this category would just be how fast can you perform that softlock. I don't have a video of it now, so... :/
I feel like spell-less would be a fun category. Just any%, but you don't get vengeful spirit. I mean, we already know setups to kill the baldur in crossroads with dreamshield in like 5 minutes, so I'm kinda wondering why this wasn't a category already.
This isn't the most original idea, so sorry if you've already seen this same idea a million times, but are minimum jumps/dashes okay category extensions?
Minimum dashes is pretty self-explanatory but minimum jumps is in reference to grounded jumps, wall jumps, dream block jumps, water jumps are perfectly acceptable. (basically, any jump while you aren't on ground)
I feel as if 100% should be a category, because, well, yeah.
