Persephone isn't that great, it absorbs so little health in such a long time I find it worthless. But anyway, use Gergoth, the beam will kill the locusts as they come at you. And if you haven't yet, go to Hammer's equipment shop and stock up on 9 potions, high potions, mind ups and high mind ups.
Also try using Erinys or Mandragora, both are Bullet souls, they are extremely powerful, and they cover a wide range of damage. Plus, Abbadon is weak to Light attacks, so Erinys is probably a better bet than Mandragora.

Been here since February 2004. It's May 2022 as of writing this. Wish Rich would revive this place. Guess I'm only here for the nostalgia now.
