Wow, this seems like a cooler version of my last playthrough with a more marketable title, is there anything else a playthrough like this forces you to do? Sorry I havent watched the vid yet since I'm at work, I'll try to sneak it in though, your stuff is always really interesting.
I did technically use magnesis to kill some of those floaty bois going up to Rudania with Yunobo and didn't know of a way to get off Plateau without unlocking the runes so definitely not 100% the same, that's for sure.
Thanks for sharing the method you used, what keeps you motivated to keep trying new/more difficult playthroughs? I got really burnt out by my "Peasant Mode" go and it almost took me a year because I couldn't enjoy the game anymore after the previous restricted playthrough I did.
