First off if you notice the Crystal Tower is the Labyrinth of the Ancients so maybe ancient shield is there. The item could just be in the database because it is in the game yet not obtainable maybe you could obtain it in Beta, but it was removed. And no one has it so no one knows how or when it can come out. Here is an example of an Item no one can get right now unless they have it from before http://na.finalfantasyxiv.com/lodest...m/81aebdee4eb/ and yeah it's in the database. So maybe it's just not out yet. Or it is buried deep in the the game somewhere. Maybe its from some achievement reward or like i said , a Crystal Tower drop. They said it would be item level 80 armors but maybe 90 weapons since Allagan will drop 95.
