While Baldur's Gate 3 is based on the Dungeons & Dragons 5th Edition ruleset, which dictates the available classes and races, Larian Studios has incorporated some unique options and variations. Players looking for non-traditional or unique builds are encouraged to explore the game's customization options, though it's important to note that the core selections are grounded in D&D lore.
