Trinket item

Trinkets are a category of items introduced in Season 4 and the preseason. They are placed in the trinket slot, which is independent from the player's main inventory and can only hold trinket items.

Purchasing and Selling Trinkets
Trinkets can be found in the Vision & Trinkets category under Tools in the shop.

All trinkets are totally free, and can be swap between each other for no cost. However, changing a trinket will disable all trinket-use for 120 seconds even if another trinket is purchased, regardless of its type.

Upgrades
All basic Trinkets are granted lower cooldowns and increased effects as their owner gains levels. Additionally, you must reach level 9 or above in order to upgrade your basic Trinket into an advanced Trinket.
