Hey fellow Final Fantasy X explorer! When progressing through the sphere grid, prioritize unlocking character’s key abilities first before branching out to other nodes to make them more effective in battles. Don’t be afraid to backtrack to grab important stat boosts or powerful skills.

For side quests, make sure to complete the Monster Arena challenges to unlock some of the best items and equipment in the game. Also, don’t miss out on the Celestial Weapons for each character, as they are powerful and essential for end-game content.

When it comes to character builds, focus on maximizing each character’s strengths. For example, Tidus is great for agility and speed, so boosting his accuracy and evasion can make him a powerhouse. Customize your characters’ abilities to complement each other in battles for a well-rounded team. Happy exploring!
