Multiclass a 5th Level Fighter?

Hi everyone. Forgive my ignorance.  One of my players built his character using the Roll20 sheet with the charactermancer.  His character is currently a 5th Level fighter who wants to take 1 Level Cleric.  How can he edit his sheet? Thank you. Alex

You can click the cogwheel on the top-right corner of the character sheet (where the buttons for core/spells/bio are) to open the character sheet settings. There, on the left side, you can see a section about multiclassing, where you can add cleric as a secondary class. In the bottom-right box of the settings page you can find a button to open the level-up charactermancer, which also allows you to add a second class to the character in the process of leveling up.

Thank you.

You're welcome :)
