I plan on attempting this run pretty soon and wonder if rerouting it would help, opinions on this?

Nmg Any% isn't a category. NMG and Any% are two completely different meanings and categories. Damageless any% isn't possible I believe.

ye sorry bout that i just remember them not being separate things, and any % didn’t have walk through walls. I haven’t run like since then, so I mean just damageless nmg

I attempted a Damageless% NMG a month or 2 ago, and failed at the sun fight I'm sure it's doable though

Yeah I need to practice sun first since I literally feel the pressure of undertale during it
