Item

An item is an artifact/object carried by champions to enhance their performance on the Fields of Justice. Items are only obtainable through the item shop located at the resurrection platform, where they are displayed in five main categories (by their effect). They can also be divided by their tier: basic, advanced and legendary. A champion can only carry 6 items at a time, making the selection of items an important part of achieving victory. You can pick among 107 items in Classic mode (including consumables), giving at least 2,392,407,864 different combinations. Doran's and gold per 10 items can be sold for 50% of their cost; all other items for 70%.

Effectss
Every item in the game grants one or more primary statistics to a champion. More expensive items may also grant one or two secondary effects. Sometimes an effect is listed as unique, which means that if two identical items are bought, the unique effect will apply only once (also referred to as a non-stackable effect). Unique effects from related but non-identical items will generally stack, with some a few exceptions (such as the bonus mana passives on, and ; and the proc effect on ,  and ).

Primary effects
Primary effects affect the champions themselves, and can increase the following statistics:
 * Ability power

Secondary effects
Secondary effects are divided into three categories:
 * 1) Actives: An item that has an ability which can be activated by clicking on the item icon in the inventory or using the number pad keys 1-6 by default.
 * 2) Auras: It can be an area of effect buff that affects all ally units or champions, or a debuff that affects all enemies units or champions.
 * 3) Passives: An item that has an ability that works automatically, like a passive ability. Many passives are Unique, meaning that they will not stack multiple times from the same item.
