Matthew Mercer's catchphrase when the players defeat a challenge

Matthew Miller, known by stage name Matthew Mercer, is a voice actor, a member of the main cast of Critical Role, and the chief creative officer at Critical Role Productions LLC. He is the Dungeon Master of the main Critical Role campaigns.

He is also a member of the board of directors for the Critical Role Foundation and the creative advisor at Darrington Press LLC. He has also been the Dungeon Master for several special episodes. He also voices Sylas Briarwood in The Legend of Vox Machina as well as additional voices.

Critical Role Productions


In 2012, Liam O'Brien asked Matthew Mercer to run a D&D one-shot for his birthday. At the time, Matthew kept telling Liam about the D&D game he was running and often invited Liam to join. The game then became an ongoing Pathfinder campaign.

When Matt created the campaign that eventually became Critical Role, he made up his own world, 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.

Matt creating a battlemap

In preparation for the streamed series, 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 subclass didn't exist in 5th Edition D&D. The two of them took a full day to switch over the character and all of his stats and abilities.

Main campaigns

At the beginning of the series, Matt created custom battlemaps by drawing grids on paper. He eventually upgraded to three-dimensional maps, and spends time every week assembling battlemaps from the hundreds of pieces he has collected over the years. He hand-crafted some of the map elements, and has painted some minis by hand.[2]

During the show, Matt is responsible for the music, and with the new Campaign Three set, the ambiant lighting.

In an open letter published a few days before the Campaign Three premiere, Matthew Mercer confirmed that he was working with cultural and sensitivity consultants "throughout the worldbuilding and presentation of Marquet" to ensure that aspects of the continent of Marquet, the main setting for the campaign, would be "lending a familiarity and celebrating aspects of those same languages and cultures without appropriating them".[3]

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.[18] He has revealed in multiple interviews that he suffers from body dysmorphic disorder and has always struggled with his physical appearance.[19][20]

As a freshman at high school, approximately 14 years old,[21] Matt joined popular arts club, where he started playing Dungeons & Dragons[22] Although he promptly fell in love with the game, most players at the table preferred mechanical aspects of DnD, which did not caught Matt's immediate interest. Seeing the potential and the instruments DnD provided for storytellers, he began DMing his own campaign wtih narrative incline.[23][24]

Before his aspiration for acting, in his middle years school Matthew wanted to be a chemist and during his high school an illustrator.[25]

When Matt began pursuing acting, he discovered that there were many Matt Millers in the industry. To make his name more memorable, he decided to change it from Miller to Mercer, a family name dated three generations back.[26]

Starting with "Strangers with Candy" era in the late 90s, Matthew Mercer is a long time fan of Stephen Colbert[27] and had him on dream DnD guest star list since July 2015.[28]

On October 21, 2017,[29] in between campaigns One and Two, Matt married Marisha Ray. They live together with their dog Omar and previously had a bird Dagon. 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.[30]

Matt has done cosplay as a hobby for years. He even cosplayed as Pumat Sol during a convention, and again for a Twitch ad that sometimes plays during episode breaks.
