This is the only way to farm Magic Spheres in FFX. Jumbo Flan is unlocked after capturing three of each Flan-type fiend in Spira. Here’s a list of what you’ll need:
Water Flan (in Besaid) Thunder Flan (on Mushroom Rock Road) Snow Flan (on the Djose Highroad) Ice Flan (on Lake Macalania) Flame Flan (in the Calm Lands) Dark Flan (on Mt. Gagazet)
Battling the Jumbo Flan
Annoyingly, the Jumbo Flan is immune to physical attacks. This means that you’ll be leaning pretty heavily on your spells and summons to get the job done. Any of Rikku’s elemental Mixes work as well. Farming Jumbo Flan is one of the slowest farms in the game because of this limitation. One of the quicker ways to get through it is to summon Anima, juice it with Haste and Regen, and then continuously use its Pain ability. If Yuna’s magic is at (or above) 170, then you can deal 99999 damage each time. To make things easier, teach Anima Haste and Dispel so you can move faster and get rid of Jumbo Flan’s Regen whenever it casts it. Teaching Haste to an Aeon requires 10 Chocobo Feathers. And teaching Dispel to an Aeon requires 3 Purifying Salts.
What Are Magic Spheres Used For?
These enchanted orbs turn an empty node on the Sphere Grid into a Magic +4. This is really the only use for them in the game. Combine them with Clear Spheres (which empties a node) and you can turn all your lower Magic Nodes into +4s and cap your magic stat. It’s all about that min-maxing, baby!
Ultimately, Are These Worth Farming?
No, not really. Magic starts to take a backseat to physical attacks as the game progresses, especially if you’re going deep into the endgame stuff. And unless you break your HP limit (which I don’t recommend) then you can easily heal up to 9999 with just what’s on the Grid already. The only reason to really farm Magic Spheres is if you want to see 255 in all your character stats, or if you’re just all about having big numbers. Honestly though, a few long battles with Jumbo Flan and you’ll probably start rethinking farming Magic Spheres anyways.
