An item is an artifact/object carried by champions to enhance their performance on the Fields of Justice. A champion can only carry six items at a time, making the selection of items an important part of achieving victory. Items are only obtainable through the item shop located at the resurrection platform. This is also where items are sold, returning 70% of the total gold spent to obtain them, with the only exceptions being , , , , , and all items that increase a champion's gold per 10 stat, each of which returns 50% of their total cost.
Items are divided into four basic categories: basic, advanced, legendary, and consumable. A basic item does not require any other items to be purchased. If an item requires the purchase of at least one specific basic item before it can be purchased, that item is considered an advanced item. All basic items required for the purchase of advanced items are consumed when the advanced item is purchased. The same is true for legendary items, which require the purchase of at least one advanced item. No item requires the purchase of a legendary item, making them the final tier in any item recipe.
Consumable items are different from other item types in two ways. First, consumable items may be stacked up to five times in one item slot while other items require multiple item slots for multiple purchases. Secondly, consumable items may be expended to perform a specific function.
Every non-consumable item in the game grants one or more statistic to a champion that holds it. These statistics are considered either primary or secondary.
Primary effects affect the champion's stats in some positive way. Every non-consumable item in the game grants some form of stat increase as a primary effect, with the one exception of Mana Manipulator, which grants all its stats as an aura.
Secondary effects additional effects that are provided by an item being in a champion's inventory. Most secondary effect on legendary items that are also on advanced items in their recipe (such as the bonus mana passives on and ) do not stack if both the secondary item and the legendary item are held at the same time. Some secondary effects are labeled unique, meaning that the effect will not increase if multiples of the same item are held at the same time.
Secondary effects are divided into three categories:
Aura effects are buffs or debuffs that effect nearby champions. All aura effects are unique. If two champions on the same team hold an item that increased the stats of allied champions, they will both receive double the effects of the aura. This stacking effect does not increase if a third aura item is purchased by a teammate.
A passive attribute is an ability that works automatically, like an innate ability on a champion. Many passives are unique. Some items have basic champion stats such as spell vamp and armor penetration as unique passives, preventing players from stacking the item to exploit the stat.
