Hey fellow Final Fantasy X explorers! When it comes to side quests, make sure to visit the Monster Arena in the Calm Lands. By capturing monsters and battling in the arena, you can earn valuable items and unlock powerful abilities for your characters.

Don’t forget about the Celestial Weapons side quest. Each character has a unique ultimate weapon with powerful abilities. To unlock these weapons, you’ll need to complete various tasks like dodging lightning bolts in the Thunder Plains or racing chocobos in the Calm Lands.

Lastly, be on the lookout for the Al Bhed Primers scattered throughout Spira. Collecting all of them will not only help you understand the Al Bhed language but also unlock additional dialogue in the game. Happy questing!
