From publisher blurb:
The Unusual Encounters is a selection of 19 strange and unusual denizens for your dungeon crawl role playing game. Only in this tome can you learn of the curious Dungeon Pope, the dreadful Eye of Introversion, and terrible Pseudo-Lich, or the mysterious Highly Enchanted Cocktail.
This book contains 19 original illustrations and short write ups for each monster, plus a few random tables. If you're a fan of old-school dungeon crawls with a bit of quirkiness and a lot of randomness, this is for you.
