A tip of the hat to Ravenloft's "Dread Companions" in the spirit of Studio Arthaus' rendition of the Land of Mists. While some GMs might argue that the Agate Companion is perhaps "too good for its price", players who think they can use it as a mere "cheap boost" to their animals will soon find themselves in a destructive relationship the likes of 80's novel Christine. Giving the GM full control of your animal companion under the premise of making your life difficult comes with a price. Your closest friend might soon become your undoing.
