fSTR is in fact MORE potent for 1-handers than it is for 2-handers, due to the lower base damage on 1H weapons. You get more benefit from raising base damage on a low-damage weapon like a Dagger or Katana than you would on something like a Scythe or a Great Katana.
Go ahead and use it, too bad you're doing it wrong. Glad there's always people out there to support crafters though.
Spike Necklace gives between 1-2 accuracy, 3STR (so likely a boost to fSTR, which is more than people realize), 1-2 attack, and not to mention that the person talking down fSTR is a 100 Goldsmith.
Nice try talking down REAL statistics to make a profit off of stupid people Tankjr.
Buy the NQ, use it till 21, then ditch it. Spike isn't a LOT better, but this price tag is ridiculous.
