well sh has got only one offensive skill - checkmate wich uses dark attribute
dark stones are very expensive compare to fire/water stones
so what do you think about making a sword with water attribute instead of dark
if dark is better on end game ill make dark just need to be sure of that

dark rofl

afaik almost all spells and skill [even checkmate] are non-attributal, though you got dark weapon and dark weapon toggle and maybe dark flame/soul of pain skills are dark attribute, so....yeah dark, but it won't have too much effect

you can enchant the nukes for dark element...
