Teamfight Tactics – Item Duplication Bug/Glitch
Class-specific items created using the spatula can be easily duplicated in TFT by dragging the item to a champion of the same class (Demon to Demon, for example). If done correctly, will duplicate the item. By dragging and releasing the item to the respective champion, catching the item in mid-air shortly after, and repeating the process, you can get the item duplicated if done fast enough.
You’ll know if the item is duplicated if either another one is sent to your item bench or if you notice your cursor looks like it is holding an item without there visually being an item in which you can click the champion. A duplicate will go to your item bench. The frequency of the bug varies on how fast you can do the first and second step; if you don’t know what you’re doing, you can expect it to succeed around 5-10% of the time, and if you know what you’re doing, it goes up to around 50-75%.
