Baldur's Gate 3 is drawn from Dungeons and Dragons and specifically draws its spells, classes, and subclasses from the Dungeons and Dragons' 2014 Player's Handbook. The 2014 Player's Handbook served as the basis of all gameplay for an entire decade of Dungeons and Dragons, and its gameplay and classes served as the baseline for Baldur's Gate 3's own classes, spells, and mechanics, including encounters.
