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 :D

Here's a Speedsouls Save Organizer that allows you to practice anything: https://wiki.speedsouls.com/SpeedSouls_-_Save_Organizer Also if you have any other questions related to speedruns, feel free to join our Discord server - http://discord.speedsouls.com

Will this ban me if i play online?

Simply switching savefiles will not get you banned. But if some of them have invalid items or the like, you could have a small risk. Always better to play offline when practicing (and it's obviously necessary for doing runs).
