The Amulet of Betrayal magic item from Chains of Asmodeus (an adventure by Arcanum Worlds, published by Wizards of the Coast as an Extra Life charity release) says:
You can use a bonus action to move one of the following conditions from yourself to an ally within 60 feet of you: blinded, deafened, frightened, poisoned, stunned, exhaustion. When transferring exhaustion, move all your exhaustion levels. If the chosen ally isimmune to a transferred condition, the transfer fails.
But when you are stunned you can't use bonus actions - so how could it work on the stunned condition?
