Hey there, fellow Final Fantasy X enthusiast! When it comes to character builds, customization is key. Each character has their strengths and specialties, so it’s important to play to those. For example, Tidus excels in agility and speed, making him a great choice for physical damage dealers.

A popular build for Tidus is to focus on the “Spiral Cut” and “Quick Hit” abilities on the Sphere Grid to maximize his damage output and agility in battles.

On the other hand, Lulu is a powerful black mage, so investing in her magic abilities on the Sphere Grid will allow her to unleash devastating spells on enemies.

Remember to mix and match abilities to create a balanced party that can handle various situations. Experiment with different builds to find what works best for your playstyle and enjoy the journey in Spira!
