Disc 4 crit-rate, disc 6 impact, 4p sig 2p ATK. This exactly hits the ATK requirement while having enough crit-rate to not feel completely ass.

Not sure if I should go impact disc 6 to begin with though. But I think for now this is fine. Also I don't have the core levels yet (past 1), so I probably overshot the ATK a bit, now that I think about it.. I should do that real quick.
