This new guidebook is specifically designed to make travel to other planes of existence an easy part of any D&D campaign. The rules are written in a modular fashion, allowing players and Dungeon Masters alike the ability to choose only the material most suited to their current campaign. Considered a complementary product to Manual of the Planes, this title contains a wealth of new material, including new rules subsets, player races, feats, spells, magic items, equipment, and vehicles.
