I am glad it helped you
You only have to make supplement, and talk to Crayl at home (you may need o lvl him up). Then simply advance to chapter 6 talk to him nad quest is done.
As for Deadbeat, i only used it to lvl up Aht who was far behind in xp; iam regretting it. I dont use speedhack or moneyhack game is easy enough, Iam in Chapter 6 now, with characters around lvl 25.
Spoiler tip:
Of course there are exceptions - Uya is on 30, he so damn good. But the MAIN TANK is Yuela - lvl 34, highly enhanced Brave Lord Armor, different good weapons that deal psych/holy/ice/fire/poisom d
