Jack-of-all-Trades Trophy in Baldur's Gate 3

Multiclass into every class in one playthrough without asking Withers to change your character.

Multiclassing means taking a level in a new class instead of the one you have. On the level-up screen, add a class instead of advancing a current one. The trophy needs one character with a level in each of the twelve classes, so a level 12 character with twelve different classes. The checklist keeps track of them.

The character does not have to be yours. Once your party reaches level 12:

Hire a hireling from Withers, the skeleton at your camp, for 100 gold (see Outsourcing), or take a companion you have never used, who is still at level 1.
Level them up to 12, choosing a class they do not have yet at every level.

Watch out

Pay Withers for no respec (a change of a character's class) until the trophy has unlocked. After a respec it may not unlock.
Explorer difficulty does not allow multiclassing. Play on Balanced or Tactician.
