I dont think this has ben done before, and Im too lazy to search it, but the Snarby cap and coat have it, why not the shield? I THOUGHT I was getting some shadow D when I got the Bristling Buckler and the upgrade recipes, until I went on the wiki. I DO NOT WANT TO WASTE 100K CR TRYING TO GET A SHADOW UV!!!
I think all the people who have gotten the snarby line have had some issue with this. OOO PLEASE PATCH!
If you want to use logic, Snarbolax, as a beast, resists elemental, not shadow or piercing.
