An alternative / fix to the krono selling inflation problem with these could be as simple as making it like the armor. It's no drop, you right click it to select a reward. Then, you still have to earn it as a grouper (get lucky of course), and, you may get lucky and find a rot (like now with EoK Rot gear). you could even up the drop rate since it is no drop. I mean really, if these items were not in game, or no drop, would Krono even be that hot of a commodity?
