Allow us the ability to rebox Narchillia weapons once a month, or on a 1 time quest incase we decide we no longer want to play the class we opened the box with.

It would certainly be nice if the once per family items could be swapped between characters. I still have my three completely useless cliff items because i opened them on one character and that can never be changed. Even weapon exchange items would be crap for narchillan. It would have been nice if the narchillin weapons were somehow universal, and could be swapped at will. Especially given they not even a power boost, just an extra set.

i like that they exist in the game now, and think we need more of this kind of stuff, alternatives, but it wasnt implimented in a useful fashion :/

This was possible with the old 1-per-family abyssal weapons and would make a lot of sense for the Narchilla weapons too.
