Stat

Stats (abbreviated from Statistics) or attributes are values that indicate how good an item is in a certain area. There are two main types of stats: primary stats, appearing in the Primary Basket; and secondary stats, appearing in the Secondary Basket.
An item's stats are usually randomized between an upper bound and a lower bound.
