Level up a character
Step 1: Click Level up on the character sheet
Open the character sheet for the character you want to advance. The character's current class and level appear beneath their name.
Click Level up, the button beside Long rest and Short rest.
Step 2: Select a class and apply the level up
The Level Up window opens and asks which class to level up.
Under Select a class to level up, check the class. A character with a single class has it selected already.
Click Apply to confirm. If the window first shows No parameters in this section, click Apply once to reach the class choice.
Step 3: Check the updated character sheet
The window closes and the sheet recalculates. The character's new level appears beneath their name.
Verify the updated hit points and hit dice values on the sheet to confirm the level was applied correctly.
