I BEAT MALENIA!!!
Sorry if anyone finds this stupid, but I just wanted to share this and read about your experiences, just for fun.
I think I made like 140 attempts, no mimic tear, no major runes, just me, my raptor talons and bleeding.
I'm aware that it's one of the most broken builds against her, but beating her 1vs1 on equal terms I think is priceless, emotions that only soulslikes can give you.
Advice for those who have to face her, don't give up!!
