Where do you get onions in ff12?

Early Game:

* The Great Crystal: You can find a few onions in the northern part of the Great Crystal area, near where the sandworm appears. You can spot them on the ground.

* Dalan's Tomb: You can find some onions in a chest within Dalan's Tomb, although they are not guaranteed to be there.

Mid-Game:

* Cerobi Steppe: Onions can be found in chests throughout the Cerobi Steppe. Check the chests around the "Astromon's Lair" area.

Late Game:

* The Pharos: You can find onions in chests within The Pharos, particularly on the higher floors.

Farming Onions:

* Giza Plains: The Giza Plains is a great place to farm onions using the "Treasure Hunter" gambit on a character. It's a bit time-consuming, but it's the most reliable way to get large quantities.

Note:

* Onions are relatively rare in Final Fantasy XII. You might have to spend some time exploring or farming to get a good amount of them.

* The most common use for onions is to craft the "Onion Soup" which is a powerful healing item.

I hope this helps! Let me know if you have any more questions.
