Every good Critical Role is no exception. Mercer not only adapts his campaign to suit his players, but he also tweaks the rules to keep his game moving at a faster pace for the enjoyment of his audience. As a result, Critical Role’s campaign rules have some major differences from the RAW (rules as written).

Since Critical Role is played live via Twitch, Matt Mercer has adjusted some of the rules to make things - such as crafting and resting - move faster. Mercer’s campaign is also being played by seasoned D&D veterans with high-level characters, so he uses his homebrew rules to add some extra challenges. Mercer has even created whole new character classes and specializations, which other DMs can purchase online.
