Final Fantasy X Tips

Live longer.
This tip is really help-full when fighting people like Seymour flux or enemies that mainly use attacks that only hit one person. If you customise a shield give it: Auto potion and Auto phoenix, and if you also customise a weapon giving it alchemy then you will be able to survive in fights allot longer and save allot of turns without having to use phoenix downs or potions.

What this does is makes it so you automatically use a phoenix down on a ko-od person. (The user must be alive at the time) It also makes it so you use a potion on someone when they reach critical health. Also with alchemy on your weapon that should give it the extra boost on the hp the items give you when using them.

Hope this helps
