=== Active Items ===
When buying an Active Item, players are prompted to place it into one of 4 ability slots in addition to their normal item slots. Players can only have a maximum of 4 active items in their inventory at a time, even if they have open item slots available to purchase more. Once a player has 4 active items, no more active items can be purchased until an active item is sold.
