thing to really remember is that some sort of def-piercing weapon is really important if you're thinking of doing proper damage with SBK.
if you're just a just for fun or more cost-effective build, just go cheap with full INT which easily allows you to do constant 5k+ damage in pvm...
left hand refine doesn't seem to affect damage in calculators, but imho nothing is as sexy as a +10 quad mummy MG[4] and a cheap elemental VVS haed on the right for general PVM...
