I just got to this a few days back (on Tactician no less, because I'm a self-flagellating purist I guess), and had to back out completely because there was nothing I could do. Not with my Ramza's skillset at the time, anyway.Wiegraf fight is still a pain in the ass.
I finished the game on Tactician recently. I tried to avoid random battles...
Oh not me. Once I hit the wall with Wiegraf, I started grinding like a goddamn apothecary. It probably didn't help that it had been literal decades since I played through this, and therefore didn't remember enough to really optimize my build .
That, and I just really like grinding JP. I'm a JP junkie. I like making my little grid dudes do cool things.
