where can i find this item? ive found them before but its been so long since i last played ive forgoten where to find them

Uhm, I am not sure, but it could you can get them doing the chocobo race at Remiem Temple...If I am wrong, anyone might correct me ;^.^

Yes you can get them at Remiem Temple. I found it easier to beat Shinryu in the Original monster arena though. He gives you 2 if you beat him with an overkill.

You also get 99 of them for unlocking Nemesis in the arena, and you can Bribe Malboros and Great Malboros for them.

Malboro: 540,000 Gil, 4 Wings to Discovery
Great Malboro: 1,280,000 Gil, 8 Wings to Discovery

They're very useful for leveling up because they give you the Triple AP ablility, when combined with Triple Overdrive and Overdrive > Ap, allowing you to get upwards of 150,000 AP per battle.

But the downside is that they're probably the rarest and hardest to get Items in the game.

wow cool thanks alot i remember now ^_^

This might help too, if you beat One Eye in the arena he drops a 3x AP weapon almost everytime, Use anima and you can kill him in 2 hits, the fight last for less than a min. After a half hour or so you should have a 3x weapon for everyone. Way eaiser. And sell the ones you get doubles of for at least 40,000 gil each, thought it might help.
