Expedition to Undermountain

Expedition to Undermountain is a combination sourcebook/campaign adventure for the 3.5^th-edition of Dungeons & Dragons^® ruleset.

“

No one knows what lurks in the depths of the mad archmage's halls... but you're about to find out. Day, night, I can no longer tell. Gargoyles carried off the wizard while we were roping our way down Belkram's Fall. Evendur the paladin fell beneath the axe of a blood-maddened minotaur two rests later, then Ironhewer stumbled into a magical portal and vanished screaming. We dared not follow him. It is said that these halls hide treasure beyond imagining, but even if we found Halaster's hoard in the next chamber, we are so hopelessly lost that I doubt I would live to spend a copper of it.

Description[]

Expedition to Undermountain is designed for 1^st- to 10^th-level characters and is the 3^rd-edition supplement for Undermountain.

The book is split into an Introduction, briefly describing Halaster's death and a synopsis of the adventure, the first chapter, which briefly describes Undermountain, with maps of most levels and sublevels, chapters 2-5, which are the campaign adventure, and an appendix of new creatures, such as the Eyeball Swarm, and new items, such as the Crown Adamant.

Expedition to Undermountain presents an adventure campaign designed to cover a number of levels of play. Undermountain, as it is presented here, is a huge adventuring area for any D&D campaign, containing nine main levels and more than twenty sublevels, connecting to more extensive dungeons and caverns, and ultimately to the Underdark. The book treats Undermountain as an unexplored underground region, and provides plots, power groups, and lore to enable a Dungeon Master to detail any corner of Undermountain to create a long-term adventure setting. Encounters are presented in the book, which are designed to take a party of player characters from 1st level to 10th level. With an appendix it also describes a set of new creatures, such as the Eyeball Swarm, and new items, such as the Crown Adamant.
