(I'm bad at rules and stuff but maybe together we could make it work OpieOP) So with glitchless, i'm thinking of getting rid of the Out of Bounds sections ofcourse but i feel like for example the DarkIce Mines seam walk can stay since it's not a glitch, i think you need to place the 2nd spellstone and get the 2nd Krazoa Spirit to get to cape claw, but not too sure on this. so i guess:

No OoB Seam walk in DIM is allowed No sequence breaks (if there could be any) (Probably some more but guess we have to discuss it a bit since i'm bad at this stuff :p)
