Hey fellow Final Fantasy X adventurer! When it comes to character builds, it’s essential to focus on each character’s strengths. Tidus is great for agility and speed, making him perfect for physical attacks. Make sure to unlock his Quick Hit ability for rapid strikes in battles.

For Yuna, prioritize her magic abilities on the grid to make her a powerhouse White Mage and Summoner. This will help in healing and dealing massive damage with Aeons.

Auron is your tank with high HP and strength. Enhance his abilities in that direction to make him a formidable physical attacker.

Lastly, Lulu excels in black magic. Boost her magic stat on the grid to maximize her potential in dealing elemental damage to foes. Remember to customize your characters according to your playstyle and enjoy your journey in Spira!
