Bee Wing quest question

[Summerstream]

1/2) All characters on your account can use the wings, but only one character can change the item dropped.
3) I believe character B, if they make their own wings, can change the item, but I've never made two sets of bee wings on one account. I recall that the drop is specific to each wing, though. So, if you have one wing that drops cheese, and you do the quest on a second character, you can make another wing that could drop say... royal jelly. The only problem is, you wouldn't be able to tell which wing drops which item.
4) Drop selection is account-wide.
5) You do not have to wear the wings to change the item. They can be in storage.

As a note: You can transfer the wings between accounts with a GM service, but it does not transfer the variable needed to change the item that drops.
