Trinket item

The trinket slot as it appeared in Season Four.

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.^[1]

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. Changing a trinket will remain the same cooldown as the previous trinket.

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.

Other trinkets

Item Name	Stats	Maps
Eye of the Herald	Unique – Herald's Call: Crushing the Eye of the Herald instigates a 1 second channel to summon an allied Rift Herald that sieges enemy structures. This channel cannot be interrupted. Puts the trinket on a 3-second cooldown if in combat with non-minions. Unique – Glimpse of the Void: The holder of the Eye of the Herald has Empowered Recall. This passive is lost when the Eye is crushed.	Replaces the trinket item in your trinket slot after slaying Rift Herald on Summoner's Rift
Golden Transcendence	Teleports to one of the battle platforms. Can only be used from the summoning platform. Grants invulnerability after teleporting for 1.5 seconds.	Crystal Scar (Ascension)
Poro-Snax	Serves a scrumptious scoop to a nearby Poro.	Howling Abyss
Seer Stone	Definitely Not Dominion: Reveals a 550 range area within 2500 / 3500 (based on level) range for 3 seconds (120 second cooldown). Enemy champions hit will be revealed for 5 seconds. Nexus Siege: Reveals a 550 range area within 1400 range for 3 seconds (60 second cooldown). Enemy champions hit will be revealed for 5 seconds.	Summoner's Rift (Nexus Siege) Crystal Scar (Definitely not Dominion)
Scarecrow Effigy	Consume a charge to place a visible Effigy at the target location (X range), which reveals the surrounding area. The effigy visually appears exactly as Fiddlesticks does to enemies while idle. Enemy champions that approach an effigy while having sight of it will activate it, causing the effigy to fake a random action, after which the effigy will deal 1 damage to itself. Stores one charge every 115 − 30 (based on level) seconds, up to 2 maximum charges.	Summoner's Rift and on the Howling Abyss only if Poro-Snax is used.

Strategy

Stealth Ward can be used to ensure the safety of nearby brush, or keep an eye on a position in the lane that could be quickly overrun by the presence of enemy minions.
Oracle Lens grants you true sight for the duration, revealing stealthed champions, and giving you the ability to disable any opposing wards and invisible traps, letting you counter the use of enemy trinkets and keep you and your teammates stealthed, and is a major counter to abilities such as Teemo's Noxious Trap.
Farsight Alteration grants you sight in the cast range for 5 seconds while also placing a Farsight Ward in the middle of the casted zone indefinitely, it can be used to quickly reveal a zone without getting yourself in danger. Farsight Alteration is often bought on ranged carries preferring a long range warding placement over a dangerous warding game. Seer Stone has the same mechanic but will not place a Farsight Ward.

Limitations

Since there is only one inventory slot for trinkets, a player can only own one trinket at any given moment.
Trinkets can be used as soon as they are bought, even in the 30 first seconds for the game.
