Call of the Netherdeep

Critical Role: Call of the Netherdeep is an campaign and adventure module published by Wizards of the Coast. First teased at D&D Celebration on September 26, 2021 by Chris Perkins, the book was released in hardcover and digital formats on March 15, 2022. However, due to shipping delays, the hardcover will be released in Europe on April 5, 2022.

Contents
The adventure, intended to run through levels 3 through 12, begins in Xhorhas, progresses to Ank'Harel, then moves into a new location: the Netherdeep, described as "a terrifying cross between the Far Realm and the deep ocean". Under the watchful gaze of Ruidus, twisting the fate of those who can change history, adventurers seek to release a forgotten champion of the gods, thought destroyed but instead awakened in his prison in the depths of Exandria.

The book will also include statblocks for new magical items, including those allowing characters to survive in underwater environments, and new mechanics on running a party of rival NPC characters.

When Call of the Netherdeep is released, both it and the previously published Explorer's Guide to Wildemount will be adapted for D&D Adventurer's League play.
