Magic items are rare in D&D Adventurers League, and sometimes a Player can receive a certificates for the magic item that has be found in the game.
The magic items that a player receives during an Adventurers League game also has the possibility to be traded to other players. The guidelines state that it is a 1 for 1 trade of the same rarity, and the item must be “tradeable.” A certificate that can be traded will have a different backing with a Trade Log, so that names and signatures of new owners can be filled.
This creates a very static system with magic items only given out to one player per game, and as a character increases in levels he may have an item that other players don’t want, or can’t be traded.
But at Winter Fantasy Convention in Fort Wayne, Indiana, there will be a booth at the convention that allows magic items to be returned and traded with the Wizards of the Coast staff. This is a debut event, but is planned to be repeated at other conventions. See the flyer below:
