Matthew Mercer's catchphrase when the players defeat a challenge

Matthew Miller, known by stage name Matthew Mercer,[3] (@matthewmercer) is a voice actor and the Dungeon Master (DM) for the show Critical Role,[4] as well as member of the board of directors for the Critical Role Foundation.


Matt began DMing in his freshman year of high school after playing in a campaign with a particularly bad DM.[5]

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.[6]

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.

Matt created several custom supplementals for Dungeons & Dragons, 5th edition, some of which are available on the Dungeon Masters Guild:

Personal Life

At a young age, Matt suffered from a stutter. His father, who also stuttered, got him a speech therapist who reduced the effects to the point that only certain words trigger it.[17]

Matt Mercer suffers from body dysmorphic disorder and has always struggled with his physical appearance.[18][19]

On October 21, 2017, in between campaigns, Matt married Marisha Ray. For their third anniversary, Matt shared some video highlights from his engagement to Marisha. He created a fake escape room with the help of friends, where she had to solve puzzles and fight a monster before he proposed to her.

Matt's Player Characters

Although Matt is the Dungeon Master for the main campaigns of Critical Role, he occasionally gets to be a player when someone else takes over the DM/GM chair. These are the characters he has played as so far.

Matt has also played as a player on two separate occasions on CollegeHumor DnD show Dimension 20. The first time being Leiland in Escape from the Bloodkeep and the second time being Jack in Pirates of Leviathan.
