Book of Encounters & Lairs
A d20 roleplaying supplement for Games Masters preparing adventures in the wilderness and other dangerous areas. It includes encounter tables organized by terrain and Challenge Rating, guidance for scaling creatures and Non-Player Characters, and pre-written scenarios featuring a range of monsters. The scenarios present creatures both as encounters and within their lairs, with advice on designing believable locations, developing regional ecology, and linking separate situations into a coherent campaign. A dedicated section covers planning and running more engaging encounters.
