From publisher blurb: The next installment of the Terrain Enchiridions series is here! Swamps can be a dangerous place. The unforgiving terrain, the possibility of losing your way, the biting insects, the unrelenting oppressiveness. And now a whole host of creatures that you might encounter! 14 new creatures ideally suited to swamps, marshes, and bogs, one for each type of creature in the Monster Manual. Plenty to surprise, scare, sand delight your players! Ranging from CR 1/4 to 20, experience a variety of creatures at home in the swamps, including the cute but deadly Batakhalik, or swamp otterfolk (a possible playable race), the horrific Boo Hag (including info on their covens), the devious Marsh Wraiths (undead tricksters), the nightmare-inducing Silt Lurker (another aberration you won’t soon forget), and the tremendous Muck Dragon (with stats from wyrmling to ancient).
