As a Final Fantasy X enthusiast, I love delving into character builds! For Tidus, I focus on agility and speed nodes to maximize his turn frequency in battles. For Yuna, I prioritize her white magic skills to make her an efficient healer. Auron shines with his strength and HP nodes, turning him into a powerhouse on the battlefield. Wakka benefits greatly from accuracy and agility nodes, perfect for taking down those pesky flying enemies. Remember, experimenting with different paths on the sphere grid can lead to unique and powerful character builds!
