The Dungeon Master's Guide 2 core rulebook for the Dungeons & Dragons Roleplaying Game features advice and rules for Dungeon Masters of all levels of experience, with a particular focus on running adventures and campaigns in the paragon tier (levels 11–20). It includes advanced encounter-building tools (including traps and skill challenges), storytelling tips to bring your game to life, new monster frameworks to help you craft the perfect villain, example campaign arcs, a comprehensive look at skill challenges, and a detailed "home base" for paragon-tier adventurers—the interplanar city of Sigil.
