Final Fantasy X Tips

Profit off Gil
Buy like 50 soft,holy water,or whatever is used in customizing your weapons.......Then buy a armor or a weapon that has AT LEAST 2 blank spaces(i'd perfer buying a tetra sheild on the airship or somewhere else close to the beigging of the game)(after you have the airship)Then fill up the blanks with like Stoneproof or like HP+10,30...or MP+10,30...or cast 1 MP or something and then go sell it IN KILLIKA to that old lady....she gave me more gil for my armor,weapon i should make about 3000-50000 gil in profit!!!!!!!
