Dark Souls (aka Project Dark)

[Goat]

BK sword requires around 20 str and 18 (or was it 14) dex iirc. If you want you could raise your dex and str to its minimum requirements, just so you can utilize it while you don't have any final weapon setup yet. Even at minimum, most enemies will die in 1-2 hits with it. Or if you're lucky, you might get a Black Knight Halberd.

Then you can prolly work on elemental weapons if you want to focus on PvE in the meantime. What I did was downgrade the Lightning Spear to Spear +10 when I got my Lightning Zwei maxed. Still haven't thought of which element/attribute I should raise the LS again though.
