God Ramza is an incredibly powerful Ramza with or without weapons. To get him, first you must master Squire, Monk, Samurai, and Knight. You must also be at the highest job level with these classes. Set up Ramza like this:

Monk Class
Secondary Skill:Guts
Reaction:Blade Grasp
Support:Equip Armor
Movement:Move +1

Constantly use Scream in battle and equip Ramza with the Bracer as an Accessory and eventually you'll end up with a Ramza that does up to 999 damage on human Units and is almost untouchable.
