The best Baldur’s Gate 3 mods add everything from new spells to altered BG3 classes, races from another world, hairstyles, dog armor, and a whole lot more. The BG3 community’s biggest focus, aside from new cosmetic options, is bringing more of Dungeons and Dragons 5e into Larian’s game or expanding on what Larian already implemented, so while some mods change the game completely, most just act as natural complements to the base game experience.
