In D&D Adventurers League, if two players are not playing at the same table, I know that they can still trade magic items if they spend downtime days.
How does this work? Do the players just have to agree that they are trading the items and then they each mark it on their character sheets, or is there some other record that must be created (e.g. the players have to fill out a form?) I know that it used to be that the magic items were on certificates so you would have to physically trade the certificate, but I don't think that they have the certificates any more.
Also, if the players don't have to have the physical certificates, do the players even have to be in the same physical location to do it? Or can two players negotiate a magic item trade completely over the Internet?
Also, can two characters both played by the same player still trade magic items between each other? (Of course they would still have to spend downtime days because the same player can't play two characters at one table) I know that you can't just give your other character a magic item, it has to be a trade, right? Do Potions of Healing count for this - i.e. if I had characters Alice and Bob, and Alice had a magic item that would work really well for Bob's character but Bob didn't have any magic items, I could just have Bob buy a potion of healing and trade it to Alice for the item? Would you be allowed to do that?
