Multiclassing Synergies

If you're a Baldur's Gate 3 fan but have never really dipped your toe into the world of tabletop Dungeons & Dragons, you might be wondering what multiclassing is. Multiclassing allows you to take multiple classes at the same time, but with one caveat—you must split your levels between the classes you multiclass in. While multiclassing has its downsides, it also has a lot of positives. In this article, we go over the multiclassing basics, how to multiclass, and some synergies to try out in your next BG3 game.

Multiclassing in Baldur's Gate 3

In BG3, multiclassing allows you to level up another class alongside your main one. Your levels will be split between the two classes in any way you want, and you'll only get the skills, abilities, and spells for the level you are in each class. Multiclassing is great for versatility or min-maxing the game.

What is multiclassing? Multiclassing is taking levels in a different class than your starting class. For example, if you started the game as a Bard but decided to take a few levels of Sorcerer, that would be considered multiclassing. One thing to note, however, is that for each level you take away from your main class, there are spells and abilities you won't be able to use.
- When multiclassing, you'll only be able to use a class's abilities up to the level you have in it. So, if you're level 5 but took 3 levels in Bard and 2 in Sorcerer, you'll only be able to do the actions that a level 3 Bard or a level 2 Sorcerer can do.
- Unlike Dungeons & Dragons , there are no stat requirements to multiclass in BG3. ^{[1]

Why would I want to multiclass? There are a few reasons you might want to multiclass:
- To be more versatile. If you build your character right, a multiclassed character can have access to a lot of spells and abilities they might not normally have.
- To make a crazy build. Many BG3 players have fun making silly character builds to push the limits of what the game allows.
- To get an achievement. To get the "Jack of All Trades" achievement, you must multiclass into 12 different classes without respecing your character.

What should I know before multiclassing? While there are no rules on how you have to multiclass, it's best if you have a pretty good handle on how each D&D/BG3 class works. This will help you understand how different classes synergize together and what spells or abilities are the best to take. You can multiclass however you want, of course, but it might get costly to keep respecing with Withers at camp. Here are a few other tips to know before you start multiclassing:
- To get Heavy Armor Proficiency without expending a feat, you must start as a class that has it (such as a Life Domain Cleric). This is why you'll see some builds listed as "Cleric 1/Sorcerer 11" for example.
- Fighters get Action Surge at level 2, which allows you to take another action during your turn once per short/long rest.
- Fighters, Rangers, Paladins, Pact of the Blade Warlocks get an extra attack at level 5. However, these extra attacks don't stack. For example, if you multiclass into Fighter 5 and Ranger 5, you won't get two additional attacks.
- It's a good idea to take ability score compatibility into account when creating a multiclass character. For example, Bard and Sorcerer both use Charisma as their spellcasting modifier, so multiclassing in both of these classes means you can focus your stats on Charisma without messing up the spellcasting stat of one of your classes.
