Get your customer rank to about 6+ and pass the "Eyewear Inventory" bill. Go to the Battle Depot and check the glasses section. If you see "Foresight", go to it and check if there is a pre-subdued specialist already on it (orange circles). If so, buy it but do not equip it. The only thing it is good for is to move the specialist onto another piece of equipment and equip that. If you equip the glasses themselves, you will not be able to move. There is also another item with a similar glitch, called "Tainted Staff". It is usually a pre-subdued "Alchemist - 11026"
