Ha, brilliant, Bravo <img src="/ubbthreads/images/graemlins/up.gif" alt="" /> - never tried giving the duplicate to the DK <img src="/ubbthreads/images/graemlins/idea.gif" alt="" />
Kiya <off to load her save and try it out>
Edit: my chars have luck 84 and 45 - and I was only able to get 3 keys in toto (2 duplicates+original). Hmph, it's back to my random theory again. I could use the key 2x after those 2 duplicates and had no additional key - third time the mirror broke.
And same result => placing duplicates on the ground, makes them vanish <img src="/ubbthreads/images/graemlins/ouch.gif" alt="" /> - original remains on the ground.
2nd edit => tried your method Everyman => same result, maximum of 3 keys in toto.
