Hi, um I'm on Xbox so I cannot be of assistance but I thought you would like to know that there is no black titanite slab, and that Black Knight weapons upgrade with twinkling titanite, which are obtained by killing crystal lizards or the clams. Oh sorry you meant the Darksword. You could always farm or ask someone to drop you 30 humanity and offer it to Kaathe for the sword and armor. If you have the DLC I would recommend the giant ghosts as the occasionally drop twin humanities. Otherwise, the rats in the depths help.

He most likely means titanite slabs
