The Aeon Sphere Grid is a supplemental area for increasing abilities and character attributes for your Aeons during the Final Fantasy X Collaboration Event regions. It is first accessed during Dream Within a Dream, Part 3 and builds up as you progress through the rest of the Dream Within a Dream storyline.
The space is an analogue of the character development system used in Final Fantasy X. Here, attributes are directly applied as extra bonuses to either a specific Aeon, or as a general Aeon enhancement. These are applied while you have a relevant Aeon summoned, replacing what would normally be your sub-job.
Controls[]
You can access this space from the Dream Within a Dream, Episode 3, Episode 4, and Conclusion regions by tapping on the blue and gold icon near the top corner of the map screen.
When you're finished clearing and activating spaces, you can return to your story region or go to the Sphere Grid by clicking the purple icon in the top corner of the map screen.
Shows the list of Spheres you have collected, that you have not set into a Sphere Grid space.
Shows you the effects of everything you currently have activated. Use the icons on the top bar to switch between your character enhancements and the Aeon enhancements, or filter between different enhancement types.
Lists the Aeons you have available, and shows their total attributes.

- The event's return in 2020 reduced required stamina to 1 and removed battles.

- Open the Sphere List by tapping the gold icon near the top corner of the Sphere Grid Map screen. A list will show you all of your currently available spheres.
- Choose a sphere from the list. That sphere will be inserted into the space you're standing on.

- Once a sphere is inserted, it is permanent. It cannot be removed.
