The Tavern

If you are transmuted (Say into a dragon) does your shadow clone do (a) your normal UC damage, (b) your transmuted UC damage or (c) the damage of your melded weapon?

Shadow damage is based on your skill with your current weapon, or unarmed skill if unarmed. While melded, your weapon doesn't count. Note that it is not based on your "damage", only your skill levels. Being transformed does not impact your skill levels.

So, (b) is closest, but really it's none of those things because there's lots of stuff that can increase your own damage but not your shadow's damage (eg +Slay).
