Hey fellow Final Fantasy X fan! When it comes to character builds, it’s all about maximizing each character’s strengths. For Tidus, focus on agility and speed to make him a swift attacker. For Wakka, boost his accuracy and strength for long-range battles. Lulu excels in magic, so prioritize her magic stat on the sphere grid. Auron is a powerhouse, so beef up his strength and HP. Yuna is your go-to healer, so enhance her magic and MP. Lastly, Kimahri is versatile – feel free to mix and match abilities from other characters. Experiment with different paths on the sphere grid to create a well-balanced team that suits your playstyle. Good luck on your journey!
