There've been a lot of cool custom class mods released for Baldur's Gate 3 since it came out, no matter whether you want something pretty standard that just doesn't happen to be in the base game, or something that comes from the utterly bizarre cauldron of your own DnD exploits. One of the latest to arrive is defintely on the weirder side - allowing you to play as a duo by bringing along an understudy who shares your turn.
