Thats not enough, it took me too long too so ill tell you, to truly win you gotta outdrain her, farm atleast 500 common souls before the battle then the scaling might be too much because she drains depending on your xp but it cant be too low, i got 300m xp in red and 200m in vix and sam, you use the previous fight to get to around 50k health, more if possible, do the charm the mocks and just healbot red, it is a very, very slow process but you can outdrain her
