Baldur's Gate 3 Classes, Multiclass and Respec Guide

Choose among the official class roster, understand multiclass tradeoffs and use Withers to rebuild without restarting the story.

Direct answer: Start with one class until its core loop is clear. Multiclass only for a named feature you can reach, and use Withers at camp when the current ability scores, proficiencies, spells or subclass no longer support the job you want.

Do this first

  1. 01
    Name the party job before choosing a class.
  2. 02
    Check the next two class levels before multiclassing.
  3. 03
    Do not delay a key power spike without a specific payoff.
  4. 04
    Find Withers through early exploration or camp progression.
  5. 05
    Rebuild from level one, then recheck proficiencies, abilities, spells and prepared actions.

Choose by turn job

Larian lists 12 base classes and, after the final patch, 46 subclasses. The useful decision is what the character must do on a normal turn: hold space, control enemies, support allies, attack at range or deliver a short burst.

A class tier list cannot replace party context. A powerful option that duplicates an existing role may solve fewer encounters than a simpler missing tool.

Multiclass with a destination

Multiclassing trades later features in the current class for earlier features in another. Write down the exact level and feature you are buying before splitting levels.

If the payoff arrives after the campaign section you are playing, the build is still a plan rather than a current advantage.

What respec changes

Larian confirms that Withers can restart a character's build from level one and change class, subclass, proficiencies, abilities, spells and cantrips. It is a rebuild tool, not a story rewind.

After rebuilding, open every action bar and prepared-spell list. A valid level allocation can still leave the intended combat tools unprepared.

What remains fixed

The official respec explanation does not promise that every origin, race, background, appearance or narrative consequence can be replaced. Keep character-creation and story choices separate from class-level decisions.
