Hey fellow Final Fantasy X explorer! When it comes to sphere grid progression, don’t be afraid to mix and match different paths for your characters to unlock various abilities. Focus on key stats for each character – strength for physical attackers, magic for mages, agility for speed, etc.

For side quests, be sure to complete the Monster Arena challenges for some sweet rewards and to unlock new monsters for capturing. Don’t forget about the Celestial Weapons and the optional Aeons like Yojimbo and Anima. They can really up your game!

When building your characters, think long term. Plan ahead to unlock powerful abilities like Quick Hit, Holy, or Ultima. And don’t neglect your defense – abilities like Auto-Life and Protect can be lifesavers in tough battles. Happy exploring!
