This build is a fairly flexible and I will tend to switch the Zwei for a Halberd, Club or Battleaxe.
They probably aren't the best options and I intend to add more items to use.
I will on the odd occasion switch my longbow for the Black Bow of Pharis, but that would just be for luring or sniping.
All of the afore-mentioned items are +5. The Zwei is +6 and the Pyromancy Flame is +10 or so.
