Paladin Materia

[Reynhart]

I don't think it's gonna be worth it to give up on Crit and Det in favor of the slight DPS gain Fracture might give, but you never know! It might be that just having enough Skillspeed to get one Fracture, two GBs and two RAs into a FoF window might be good enough?

Don't forget that SkS also basically increase your DPS.
And, if Ariyala's weight are to be trusted, SkS is actually better than Determination when it comes to melding rank IV materias (Since rank IV offers 9 SkS over 6 Deter)
