I got burned out so I haven't made progress at all.
I booted up BS2 today, kept going and got them done in ~144 floors, currently sitting in Layer 947.
I hadn't even realized I got Chaos Blast along the way until I opened the menu to teach myself Quick Dance lmao.
Might as well keep going until Layer 999, even if I know there's nothing special past Old King.
