The Adventure Zone, Volume 4

The Adventure Zone: The Crystal Kingdom takes this #1 New York Times bestselling series to haunting new heights! All these ghosts are spooky enough, but it's downright frightening how great of a read this D&D-inspired adventure is, with tabletop antics that fans of Dimension 20 and Critical Role will adore!
A desperate call for help interrupts holiday celebrations at the Bureau of Balance, and sends Taako, Magnus and Merle on a high-stakes mission to find and Reclaim a fourth deadly relic: a powerful transmutation stone, hidden somewhere in the depths of a floating arcane laboratory that's home to the Doctors Maureen and Lucas Miller. An unknown menace has seized control of the stone, and is using it to transform the lab into a virulent pink crystal that spreads to everything it touches.
It's only a matter of time before this sparkling disaster crash-lands, but in order to find the stone and save the whole planet from being King Midased, our heroes will have to fight their way through a gauntlet of rowdy robots and crystal golems, decide whether they can trust the evasive Lucas Miller, and solve the mystery of what―or who―has put them all in peril, before there's no world left to save.
