(PS3) 4 Kings SL 1 [RESOLVED]

I know a lot of people have been doing SL 1 runs, so I decided to try one myself but I'm totally stuck on 4 Kings. I've blown so much humanity to summon Beatrice (I really want the Witch's set) that I've managed to get 2 slabs to drop from the Darkwraiths. Anyways, can someone lend a helping hand? I'll even let you have one of my slabs.

P.S. I don't care if you think my SL 1 is "not legit" because I'm summoning help - I've beaten these guys a ton of times using "normal" builds and this SL 1 run is purely for my own interest.

EDIT: Someone helped out and claimed the slab.
