Item (Teamfight Tactics)

Items can be equipped to Champions to increase their stats and grant additional effects.

Champions obtained from the carousel will start with an item, and additional items can be obtained as drops from PVE rounds. Items are stored on the bench until equipped to a champion, and selling a champion will move all items they're holding to the bench.

Champions can only hold a maximum of 3 items. Basic items will automatically combine to form Advanced items, requiring players to plan the order that they equip items to prevent unwanted combinations. There is no way to split an Advanced item into its composite parts.

The Synergy allows player to disable enemy items. Champions with items currently disabled lose the stats and effects the item give until the effects wear off. However, bonus traits added from items are not affected by Hextech. For example, a champion with item equipped will lose its 40 AP stat but not the  trait.

Item Dropping
If you sell a champion, items equipped on that champion will be dropped. If you combine champions with a total of more than 3 items, the extra items will be dropped.

If you build a trait item on a champion with the same trait, for example: building a on a, the item will be dropped from the champion. The same thing would happen from picking the champion from the Carousel. If the item provides an existing trait, player will get the champion and item separately when they return to the arena.

Item stacking
Most items can stack additively with themselves (e.g. 2 will grant twice as much shield), but some item stack multiplicatively, such as.

Explicitly non-stacking
The following items' effects cannot stack with themselves, and a champion can only equip one of the same at a time:

Standard stacking
The following items stack as one would expect:

Multiplicative stacking
The following items stack multiplicatively and have diminishing returns :

Special cases
