First, go to Ishiguros rest(zone 2),and shop.Well,for all but gunslingers, buy the icy katana as much as you can(strength+12)and go to inventory. Click on a Icy katana, and while holding it, go to the ability screen. Where the stats are(vitality,strength,magic and speed),click in that box while holding it.You will lose the item, but its stats will merge into yours. Once you use it, try not to use re-spec-you will lose the stats!!!It works. For gunslingers, just do what you can.Hey, at least i told you the cheat. hope it works for you!!! :-)
