This is crazy helpful, thanks very much!
Your statement at the end about expanding it is pretty much how I feel about it too, I think there are some big issues with how the material gathering works right now & most of the ways I can think about improving it pushes it closer to just being a worse version of noita. I think it definitely needs some ways to make what spells you get / how useful they are vary per run, at least.
I hadn't heard of Magicmaker or Mages of Mystralia, I'd like to check those out sometime.
( the rune halves the cost of the materials at either side of it btw )
