What is Multiclassing in BG3?

Multiclassing is a mechanic in Baldur’s Gate 3 that allows you the option of choosing a new class each time you level. For example, if you are playing a Bard when you reach character Level 4, you can choose to put that new level into Rogue. Consequently, you will then have three levels in Bard and one level in Rogue.

The benefit to multiclassing in BG3 is that it will allow your character to cast spells or take class actions that wouldn’t be available to them otherwise. The downside is that your levels will be split amongst classes. Therefore, you will not be able to reach some of the powerful spells and abilities that aren’t available to classes until they reach Levels 11 or 12.

Generally, it’s not advised to put one level into each available class unless you are going for the Jack-of-all-Trades achievement. However, you can make some powerful builds by putting levels into two classes as your character advances.

In the following guide, we’ll be covering all of the basics of multiclassing, including how to multiclass, why you should consider it, and suggested build and class combinations.

Multiclassing in Baldur’s Gate is a mechanic that allows your character to gain a level in a new class instead of advancing in your current class. Therefore, you can only choose to multiclass either when you gain a new level, or when you use Withers to re-roll your character.

Follow these steps from the level-up UI screen to multiclass your character in Baldur’s Gate 3:

  1. Click the small multiclass icon at the top right of the Level Up feature.
  2. A new ‘Add Class’ menu will appear, displaying all of the available classes in BG3.
    • Including which class(es) you have already chosen and how many levels you have put into them.
  3. Click to choose the second class you wish to multiclass your character into.
  4. Proceed with the leveling-up process as normal, choosing features and abilities from your new class.

If you don’t see the multiclass icon, or if you can’t click it, then it means that your difficulty setting is too low. If you are playing on Explorer difficulty, then the game does not allow you to multiclass.

However, you can easily get around this by changing the difficulty to Balanced immediately before leveling up. Next, level up your character with a different class, and then switch back to Explorer. You will have to do this each time you want to change classes, but it’s a simple way to be able to multiclass on the easy difficulty.

Why you should Multiclass in Baldur’s Gate 3

The reason you should Multiclass in BG3 is because it grants most of the benefits of that new class, while simultaneously retaining the identity and strength of your initial class. Choosing a different class can unlock different abilities, actions, or spells you wouldn’t have had access to otherwise.

However, the downside is that you won’t reach the high-level benefits some classes receive when you specialize in a single class. For example, if you multiclass a Wizard or Sorcerer then they likely won’t get access to the Disintegrate spell. This only becomes available at Level 11 for both classes, so if you put more than two levels into another class, they will miss out on it.

Therefore, it’s important that you don’t spread yourself too thin with many classes. It’s highly recommended that you stick with just two classes at a time. For certain builds, perhaps three. However, any more than that and you can lose out on additional feats, strong actions, or powerful spells.

The best class to multiclass with any build in Baldur’s Gate 3 is the Fighter class because with only two levels invested, you will receive Action Surge. This is a free action you can use once per Short Rest, and it allows you to take another action in the same turn. Moreover, at level 5 Fighters receive the Extra Attack passive feature, which lets you attack twice.

Actions represent the number of moves you can make in a combat turn or the number of times you can hit an enemy with your weapon. Gaining more of these can have a massive impact on the strength of your character and go a long way toward making fights less difficult.

Therefore, this makes the Fighter an excellent choice to combine with almost any other class. However, when you choose your levels for which class can be challenging to figure out as you are playing the game. In general, we recommend putting at least four levels into your starting class, so that you can reach your first Feat selection.
