No additional XP award in my games.
In my XP, the mirror broke after 1-2 keys - but I know of one gamer here, who was luckier => 3.
I dropped a duplicate once - and it vanished from the ground, so I lost one key. wish, I would know the correct procedure => totally random or luck, don't know. (Tried it with a high luck boost and a low one, saw no reliant result)
