I beat Malania a 2nd time with a new character. This time I didn't get so lucky and it took about 20-30 attempts even with the Mimic. The problem I have with this boss is this fucking combo:

Yes, I watched this to figure out how to dodge it. The problem is that there's not enough of a tell when she's about to do it and she loves to pull this thing out of her snatch just as you do something and it's an "Oh fuck" moment because you're too close to effectively runaway. And even this dude who does no-hit boss runs say's it's a pain in the ass to dodge it close.
Beat this bitch with Twin blades with Bleed, the White Mask, used Mohg's Great Rune just for more health and used Kukri's when she does that gay Scarlet Rot AOE.
