General Leo Edition

Dude, I do NOT have half the patience to go through EVERY SINGLE ITEM!

There seems to be a misunderstanding here. I might be wrong. Perhaps you did not notice, but Fedorajoe has already answered your question in a previous post.

You have to bet a certain item at the Colosseum, as with Shadow. There are a lot of clues along the way in the WOR as to which item and all.

Furthermore, Blue Mage Gab has a point in his post. Personally I would not want to see the answer posted here either,since it gives away the fun.:

I doubt someone will tell you where to get the item for Leo because this is the fun part at a hack. Nobody wants to kill this "fun" if you know what I mean.

I suggest you stop asking the same question and either address this to fedorajoe via PM, or figure it out on your own.
