Items

Items are in-game equipment that provide heroes with bonus attributes and special abilities. They can be purchased from several shops on the game map. Lower tier items are combined into higher tier items, usually with the help of a recipe. Heroes have six item slots in their inventory, three in their backpack, and six more in their stash. Items can be picked up and delivered to their owner with a courier.
