The Bard class has access to a wide range of features in Baldur's Gate 3, making it a great choice for multiclassing. In particular, it combines well with the three other Charisma-based spellcasting classes: the Sorcerer, Warlock, and Paladin. Of these three, it's the Paladin that can offer the Bard the most power and synergy in Baldur's Gate 3, either in a 2/10 or 6/6 combination.
