Onion Knight is a job class in Final Fantasy III. In the original NES version of Final Fantasy III, all characters began as Onion Knights, and then went on to other jobs. With the creation of the Freelancer class, the Onion Knight was no longer needed, however it remains as a hidden class that requires the player to use their Wi-Fi connection to obtain it. Onion Knights can use all magics, abilities, and weapons, except for job-specific ones, and have their own set of weapons and armor.
- Battle Command
- Magic: Cast all Magics
Obtaining the Onion Knight job class is a Wi-Fi sidequest on the Nintendo DS. To obtain the job class you must first find seven people (real life) and register them on your Address Book, and have them do the same for you. Send seven messages to each of them, as well as sending three messages to Elder Topapa in Ur. When you've finished, return to the Mognet Moogle (one is located in each town), where you should have a distress signal. You must rescue three children for Elder Topapa, all of whom have been trapped by bombs. Once they have been defeated you will be thanked by the children, and receive a Crystal Shard and the Onion Knight job.
