Reforger

A Reforger is a consumable in Teamfight Tactics that you use on a champion to unequip all of its items at once and randomly transform them into different items. It is the main way to fix bad item combinations or fish for something better.

Reforging respects item category and quality: a completed item rerolls into another completed item, an emblem into another emblem, and so on, so you will not downgrade tiers. This makes it a controlled gamble rather than a coin flip. Players use Reforgers to escape an off-meta item, hunt for a Best-in-Slot piece, or convert an unwanted emblem into a useful one.
