Have you ever looked at two of your lions - one is your dream, but is missing something, and one is unfortunately ugly but has the marking that would complete your dream lion... but it's not a marking you can get through a normal marking applicator?
Thinking, "dang, my heir would have all of the celestial markings if i could just get that one off of that female?"

What if for GB in the Oasis, there would be a Marking Extractor that takes a chosen marking off of a lion, and stores it in the item for it to be applied to someone else? Or sold to someone who needs the marking. They could be raffle prizes, ect.

The item icon wouldn't have to be changed, maybe only the name. Maybe like, the item would be originally called Marking Extractor and after a marking is in it, its name will change to something like Marking: Brown Rosette... so that we don't have to stress out the artists! Only the coders!
(From one coder to all others, I'll see you all in hell, because that's where we're all going. No denying it.)
