Items are allowed to have as many powers as a character possesses tiers. Thus an item owned by a white belt may only have 1 power, whilst an item owned by a Green belt may have up to 3 powers. Powers must be purchased for yen and if a character with a maximum empowered item loses a tier, the most recently activated power becomes dormant until the fighter regains their old tier (if more than 1 tier is lost, more than 1 power will become dormant if necessary). Items can be given to another fighter at any time. However, a fighter may never have more than 1 "real" item at a time and may have to destroy or give away another item to keep the gift. Any powers that become dormant because of the new owners tier rank are considered lost forever. Furthermore, if an item is given away, its powers become temporary. Each time a power is used, that power is lost. When all the powers are used, the item remains "real", but the fighter must spend yen on it to add powers. A fighter may spend yen as normal to make any temporary powers permanent again.
