Hey fellow Final Fantasy X adventurer! When it comes to sphere grid progression, I recommend focusing on maximizing each character’s strengths. For Tidus, prioritize agility and speed to make him a speedy powerhouse. For Auron, beef up his strength and HP to turn him into a tank. And for Yuna, enhance her magic stats to make her an exceptional healer and summoner.

Don’t forget to complete side quests like the Monster Arena and Capture Quests to earn valuable rewards and unlock powerful abilities. Also, keep an eye out for the Celestial Weapons and Aeons hidden throughout Spira to enhance your party’s combat prowess.

Experiment with different character builds to find what works best for your playstyle. Whether you prefer physical brute force, magical mastery, or a balanced approach, there are endless possibilities to customize your party. Happy exploring!
