The Cloning Chamber description says "Adds an exact duplicate ..." which I would interpret as the new unit having the same stats as the cloned unit - e.g. if it clones a Priest / Paladin / Death Worm / Monster Hunter that has already boosted attack, the clone should start out w/ the same boosted attack. Currently it doesn't - the new, cloned unit starts out w/ the normal starting stats of the unit type. If the current behavior is intended I would suggest removing the word "exact" from the description to be more clear.
