Critical RoleCampaign 4 is officially starting on October 2, and in a shocking twist, Brennan Lee Mulligan will be the GM for the entire series. Matt Mercer will be stepping into the player’s seat in favor of Mulligan in the nextCritical Rolecampaign, though it is currently unclear if it will use theDungeons and DragonsorDaggerheartsystem.

The third campaign ofCritical Rolewrapped up on February 6, bringing some drastic changes to the world of Exandria with it. In the subsequent months,Critical Rolehas done different miniseries, one-shots, and live shows, but news about its fourth full campaign has been elusive thus far.

Now,Critical Rolehas pulled back the curtain on Campaign 4, and thrown fans some big curveballs in the process. During the first Critical Role Direct at the Indianapolis live show on August 2,Critical Roleconfirmed Campaign 4 would begin on Thursday, October 2. However, this new campaign will differ in many ways – most notably, that Brennan Lee Mulligan will be the dungeon master for the entire game, rather than long-time dungeon master Matt Mercer.

Mulligan is known for his comedy and improv work with Dropout, includingDimension 20, its own TTRPG actual play series. That said, he has previously guest starred as a DM inCritical Role’sExandria Unlimitedseries. Mercer has likewise appeared onDimension 20, and will still be a part of Campaign 4, albeit as a player, ostensibly alongside the rest of the core cast members.Dimension 20fans need not fear; Mulligan confirmed in a thread on Bluesky that he recently signed a three-year contract with Dropout, so he will still be appearing onDimension 20simultaneously with Critical Role.

There are still plenty of mysteries about Campaign 4. The teaser trailer mentioned a new story and a new world, implying it might not be a direct continuation of the story of Exandria after the story of Bells Hells. More information about the characters, setting, potential guests, and whether it will useD&DorCritical Role’s newDaggerheartTTRPG systemwill be coming in the months ahead of the campaign’s start.

This wasn’t the only thingCritical Roleannounced this week. During Gen Con, it announced tons of exciting stuff forDaggerheart, including a Homebrew Kit, a “Romantasy” campaign frame, a second season forAge of Umbra, and two new campaign settings: one designed by Eberron creator Keith Baker, and another made by formerDungeons and Dragonsdirectors Chris Perkins and Jeremy Crawford. Needless to say, it has been a great weekend for Critters.
