Best Spellcasting ClassesThe Cleric, Sorcerer, and Bard are the best spellcasting classes in Baldur's Gate 3 due to their amazing build versatility and high damage output during the early game.
Cleric - Probably the best spellcasting class of the game, boasting powerful spells as early as level 1 (in the form of Guiding Bolt and Inflict Wounds) and gaining access to the highest level of spells currently in the game at level 11. Clerics also offer great build diversity later on, allowing them to take on different roles in the party with ease.
Sorcerer - A powerful spellcasting class whose strength lies in its Metamagic modifiers. By being able to modify the nature of their spells, Sorcerers can turn some of the most mundane spells into hard-hitting magic as early as level 2. At higher levels, their damage output only grows exponentially.
Bard - Offers the best utility out of any spellcasting class as they can buff allies with their music and deal damage or offer support with their arsenal of spells. Equipped with multiple proficiencies, Bards are truly the Jack of All Trades both inside and outside of combat.
