I don't usually get into that kind of thing, but Malenia is freaking cool but hard af. So I challenged myself to do it no hit, which therefore requires to beat her a lot of times before fully mastering her pattern. But I searched a bit, and didn't found how to create a copy of my save, for resetting her again and again.
Then, I told myself that the best place to ask how to learn the pattern of a boss in view of doing it in no hit was among the speedrunners !
So I'm here, asking to you how to do it huh
Thx a lot in advance
