I am not a pro gamer, I play casually to refresh my mind after such hectic days with workload. This is my first souls game and it took me over 2 days and 200+ death to figure out what I should do, never tried solo her in the previous journeys. Exhausting 47000+ HP of her over two phases with such one shot game ending attacks of her - arguably the toughest boss in the game.

First thing is most of her attack/combo is one shot, so not to give her room, I have played super aggressively and broken her poise before she can even touch me. Specially that waterfowl dance, I tried many things, shield for that moment, freezing pot etc. - only to eventually realize that attack is the best defense. Whenever she jumps to do that game ending move, I have jumped too with her and break her poise (at 1:30 ). And ended up with no hit phase one! Second thing that bothered me much was stamina! After upgrading to 99 endurance, equipping Green Turtle Talisman, Bloodboil Aromatic and Greenburst Crystal Tear, I felt the stamina was adequate!

Second phase is even tougher, because there she can fly, use scarlet rot against me and my buffs have dried out. Still followed the same tactics, not giving her the room. And eventually I made it. She literally did not not spare me without getting good! I am so happy and accomplished today!
