Sorcerer is one of the trickiest classes in Baldur's Gate 3 to master. Building a sorcerer correctly is not the only thing needed to have a good experience when playing a sorcerer; players also need to know how to use its additional class features such as metamagic and sorcery points. As a spellcasting class, BG3 sorcerers become extremely powerful at higher levels, and their ability to manipulate spells to give them different effects shows their innate proficiency with magic.
As with all the classes in Baldur's Gate 3, getting the best playthrough from a character's build is about understanding how the class works.
