Where can I find them?
Treasure Caskets will present themselves on rare occasions only in certain areas which are part of the original FINAL FANTASY XI package. They will not appear in any expansion areas.

How do I open them?
Depending on their fortunes, adventurers may encounter either unlocked Treasure Caskets or locked ones. Unlocked caskets will open readily, allowing treasure hunters to immediately get their hands on the desired loot. Locked caskets will present a more formidable challenge, in the form of a numerical combination lock that you and your party members will have to rack your brains to solve. So sharpen those wits and have your puzzle-solving skills at the ready!

What treasures will they hold?
Unlocked caskets will contain an assortment of temporary items to assist you in your battles. Locked caskets will house a variety of equipment and items, and for the most fortunate adventurers, even exclusive equipment not to be found elsewhere!
What riches lie in wait for you? You'll just have to track down one of these Treasure Caskets and see for yourself. Happy treasure-hunting!

So now we have treasure chests for the field and not just dungeons, at least that is the way that I'm looking at it. But I'm guessing that they can put them anywhere in the old world areas. Which is a nice touch for those that don't have the expansions, but who doesn't I'm not sure at this point. The unlocked ones will be worthless, but the locked ones should be good. I find it amusing that they are going to make them into brain puzzles of sorts. Depending on the puzzle it could be a lot of fun. At least I don't need a key for them.

Don't think it's really for people without the expansions, but more so to make the old area's more popular again.
Anybody tried the caskets out yet? I haven't yet

Peace out

I wish that I was still playing FFXI (if my debit card hadn't been depleted of it's funds, that is) so that I can go find the treasure caskets.
