Unlimited back to back mimics

Royal armory map in Alexandria has perma mimic as the treasure. Kill...chest doesn't disappear. Click again, battle again.

That's on purpose. There is a trick to get it to open as a real treasure chest and there is a rare item inside.

I knew something was off about that treasure! now I need to know what to do to open it :P
