I might actually use the Shield as part of the "reward" for completing a massive dungeon crawl I'm creating for my group at the moment... seems like the perfect artifact/major magic item to spark in-character debate over whether to keep it or not

I may also use a Switchbeast and/or a Lesser Finger Horror (probably tweaked to make it less of a glass cannon) as monsters in the dungeon; anyone know where I can find Thunt's stats for Mr. Fingers?
