The Musketeer is a Fighter subclass option for Dungeons & Dragons 5th Edition.
While not necessarily historically accurate, the Musketeers that we know and love have been represented in popular media for over 150 years, beginning with Alexandre Dumas' 1844 novel. Since then, these sassy swashbucklers have been represented in film, on stage, on television and in games, further cementing them into our minds as the iconic, debonair trio (or quartet) they are hyped up to be.
