In Dungeons & Dragons, a Dungeon Master describes a setting or event, then players must roll dice to determine the outcome of the action they want their character to attempt. The final number can be influenced by the character’s skill statistics, abilities, items, and outside forces determined by the Dungeon Master. In Critical Role, characters level up after reaching a milestone determined by the DM. When leveling up, characters gain access to new abilities, new spell slots if they are a spellcaster and their maximum health increases. D&D is the greatest role-playing game of all time, and everyone will know you are a fan when you wear this 80sTees.com exclusive Critical Success Dungeons & Dragons T-Shirt!
