The sourcebook accompanies reprints of fellow possessively named tomes Xanathar’s Guide to Everything and Tasha’s Cauldron of Everything, along with a themed DM’s screen, all packaged in a slipcase for $170 (£124). The rule expansion gift set will be the only way to snag a physical copy of Mordenkainen Presents: Monsters of the Multiverse until its standalone release on an undisclosed date in 2022.

“We had our own challenges with production and shipping, which forced us to delay the release until January 25th.” “We planned to release the D&D Rules Expansion Gift Set before the holidays, but like many products in the industry, production and shipping delays forced us to move the release date,” Schuh said. She also explained why it would not be available as a wrapped gift for this year’s holiday season. Liz Schuh, head of publishing and licensing for Wizards of the Coast, appeared on the D&D Celebration livestream to premiere the upcoming sourcebook, which will appear first in a three-book gift set aimed at expanding the available game rules beyond what’s available in the player’s handbook and DM’s guide.

Mordenkainen Presents: Monsters of the Multiverse will arrive in January of next year as part of a three-book set instead of the initially intended late 2021 date. Tabletop RPG giant Dungeons & Dragons announced - and then promptly delayed - a new rulebook during a recent livestream.
