Matthew Mercer


 * This page is about the actor. For the character from a one-shot campaign, see Matthew Mercer (character).

Matthew Miller, known by stage name Matthew Mercer, (@matthewmercer) is a voice actor and the Dungeon Master (DM) for the show Critical Role, as well as member of the board of directors for the Critical Role Foundation.

Pre-Stream
Matt began DMing in his freshman year of high school after playing in a campaign with a particularly bad DM.

When Matt created the campaign that eventually became Critical Role, he made up his own world of Exandria and restructured some of the game system rules to allow for more flexibility in the storyline. He has been the Dungeon Master since the beginning of the campaign in 2012.

Before the Geek & Sundry streaming gameplay sessions, the group would meet every month to month-and-a-half for about eight hours. This infrequency was problematic, as many of the players needed to be reminded by Matt of elements of the storyline, how to play, etc.

When Matt told the other cast members about Geek & Sundry approaching him about making Critical Role, the group's reactions were recorded for posterity.

In preparation for the stream, Matt converted the game over from Pathfinder to Dungeons & Dragons, because Pathfinder combat is slower due to an abundance of various modifiers. D&D also has more name recognition. When converting their game, Matt had to create a custom fighter's Martial Archetype for Taliesin Jaffe's character, Percy, as the gunslinger doesn't exist in 5th Edition D&D. They both sat down and took a full day to switch over the character and all of his stats and abilities.

Custom D&D Materials
Matt created several custom supplementals for Dungeons & Dragons, 5th edition, some of which are available on the Dungeon Masters Guild:
 * "Blood Hunter" class Also available on D&D Beyond
 * "Lingering Soul" class
 * "College of the Maestro" for the bard class
 * "Gunslinger" Martial Archetype for the fighter class
 * "Blood Domain" for the cleric class.
 * "Path of the Juggernaut" for the barbarian class.
 * "Runechild" sorcerous Origin for the sorcerer class.
 * "Way of the Cobalt Soul" for the monk class.
 * "Oath of the Open Sea" for the paladin class.
