Is there anywhere I'm more likely to find armour with four free slots?

Yeah, I found the Omega Ruins to be the best place to find the <I> Tetra Bracer </I>, which comes with four free slots. But, the thing is, I think that everytime you acquire one of these Bracers inside the Ruins, only a specific member can wear it. So, you might get two Tetra Bracers, but only Tidus and Yuna could wear one of them.

But, once I got them, I customized that armor with Break HP Limit, Break MP Limit, and most likely HP+30%, and MP+30%

uhm.. you can buy four slotted armor on a al bhed woman i think..

and yeah just like what smokey had said you can also find some in omega ruins.

I found the most of them at the Omega Ruins, too. But it is hard to get them for all. ;)

You can buy them at the Macalania woods. The person that sells them, is standing between the save point and the thunder plains. :)

Yes, that's right. That person should be Wantz. I believe he will be there if you helped O'aka throughout the game and if you bought from him at Mt. Gagazet. That's the best bet.

Oh yeah, you�re right. It was Wantz. I couldn�t remember the name, when I wrote that. ;)

But I think, It�ll be enough, if you give O�aka a few gils in the beginning, just to find out who O�aka actually is.

Wasn�t that Wantz at the mountain Gagazet? I think, you don�t have to buy stuff from him for make him showing up at the Macalania woods.

I�m not sure anymore, but the only thing I did, was talking to them all the time. But I hardly ever bought something of them. And I never gave O�aka money again. ;)

So, I believe, Wantz just shows up (at the Macalania woods), when the time is right..... :)

I think that Wantz is O'aka's brother. Wantz tells you that O'aka has been thrown in jail for helping the party out.

Okay, thanks for the clarification, Aeris Gainsborough. I just always bought from O'aka and Wantz just to be sure, but it's good know you don't have to.
