Can I make more than one Tournesol?
As a post from Gamefaqs explains when googling FF12 multiple tournesol:
Only a few Bazaar Goods are repeatable, namely X-Potion packs, rare metals, and the like. Equipment and ammo are a no-go, unfortunately. So, no, you cannot get more than one Tournesol. There are items that can be found, earned, and purchased from Bazaar, however. These include Masamune (Hunt and Bazaar), Ultima Blade (Pharos and Bazaar) and Stoneblade (Great Crystal and Bazaar), among a few others.
