Brennan Lee Mulligan’s Critical Role run is a D&D masterclass for players

Critical Role Campaign 4 is vastly different from its previous three campaigns. The cast size has doubled, and its setting is the godless, war-torn world of Aramán. The biggest change, however, is that instead of Critical Role’s usual Dungeon Master, famed voice actor Matthew Mercer, Campaign 4 is led by Dimension 20’sBrennan Lee Mulligan.
