What about a Keraunos with BP damage Pet: acc and DA/Crit? Would that be better than a Grid?
Thats what I use for FC (only for FC) currently cause i'm too cheap to get a Was... But its also mainly cause I've had it from the era before Escha Ru'Aun. I wouldn't advise someone going out of their way to get that, but it's an option... For FC, on paper it's slightly better than NQ Was, but a tad behind Was+1.
