It’s difficult to know when to stack items in Teamfight Tactics. The game is by no means as straightforward as its MOBA counterpart when it comes to items, and developer Riot Games offers little to no help.
If you want to know which items stack in TFT, look no further. You’d normally have to sink a substantial amount of time into the game, but we’ve done the dirty work for you.
