The Warlock is one of the most front-loaded classes in Baldur's Gate 3, receiving many of its best features within levels 1-5. While this makes it a great option to dip into when multiclassing, it can make building a strong Warlock-primary multiclass a little more challenging. However, there are a few Baldur's Gate 3 classes that can synergize with a high-level Warlock build, combining features to create a whole greater than the sum of its parts.
