GAF's Nicest Lunch Thief and Nosiest Dildo Archeologist
I think to use Onion Knight effectively, master every other job, just make sure Ramza learns Ultima from Celia and Lettie, or he won't master squire!How does Onion Knight work? Is that the one that gets stronger based on how many jobs you master? Might have to give it a shot this time.
Then find the ONION ARMOR and ONION SHIELD by completing the GUARDED TEMPLE RENDEZVOUS. The rest of the equipment is in Melees.
Onion Knight is potentially the best job, making Ramza at Lv.99, Br97, Fa100, the ultimate unit in battle.
It is a time commitment for Onion Knights, so it might not be worth it to you.
