The Item Spawner Plate was an item in Fortnite Creative. It could create items of any rarity. At first it had the rarity Transcendent, the highest in the game. The rarity was changed later to Rare.
The Item Spawner Plate can spawn items, of course. You have the ability to change the duration between spawns, change the visibility size, and more.
The newer version of the Item Spawner has a feature that the plate does not have: items costs, allowing working in-game shops before vending machines were added to the game.
