Honestly 50 is more than enough, especially if you have the scadutree levels You won’t get one shotted by anything that’s not super telegraphed and should be able to live through most things. Combos that would kill you at 50 vig would also kill you at 60 too. If you need some extra survivability I recommend the dragoncrest great shield talisman which mitigates the difference in vigour

I had split stats at this point, 40 in each str, dex, int and faith - just to try things out then about 50 vigor and Talismans - warrior jar shard, Godfrey icon, dragoncrest greatshield and I can’t remember the last one right now but you can put the magic scorpion for more damage on the projectile Physik- charge attack and magic tears If you wanna see a better fight, I just beat him at level 1 with the dragon hunter great katana where it shows how to dodge moves I didn’t manage in this fight

Around 6 or 7, I remember getting to 9 after this fight. This was also before they changed the scaling in the patch

Split stats 40 each in are, dex, int and faith, the rest in vigor, mind and endurance Talismans - ritual sword, godfrey icon, axe talisman and dragoncrest greatshield Physik - magic and spiked tears

In the flask I have the charge attack tear + the magic as you said. Talismans I’m using warrior jar shard, axe talisman, dragoncrest greatshield & Godfrey icon. For the second stagger there’s a free window when she changes phase and since she entered her second phase after the stagger I had enough time to get 3 charge r2s hitting the sword and the projectile which is enough to posture break since the poise damage is still quite good after the nerf

Pure int and a little faith for this fight. Warrior jar shard, Godfrey icon, dragoncrest greatshield and gold scarab. Moonlight great sword is just one of the best weapons in the game and its damage is insane when you stack buffs
