It took over a month and 160-200 tries in regular NG. Next most was Lady Maria at 40x give or take. Didn't doubt myself ever but was disheartening, embarrassing and waste of time. Was almost ready to asked for help, but I am stubborn and every bosses I beat myself. Started at level 111 or so. Went to nightmare of Mensis and level up to 128 to come back. The pigs/hog give you like 12k blood echoes and they are easy farming for that much. Health stat is what made it work better. 4-5 visceral attacks for form 1. Use the lead potion for form 2 and just jump around. Augur of Ebrietas I used for back stab, what a lifesaver. whirlgig saw backstab was slower then the Rakuyo, but it was my highest dps weapon. I also sat infront of the TV, I could see all the moves so much better then 10' away haha.
