Has anyone used the text in the Dungeon World book describing what you do “Beyond 10th level?”
Beyond 10th Level
Once you’ve reached 10th level things change a little. When you have enough XP to go to 11th level instead you choose one of these:
• Retire to safety
• Take on an apprentice
• Change entirely to a new class
If you retire you create a new character to play instead and work with the GM to establish your place in the world. If you take on an apprentice you play a new character (the apprentice) alongside your current character, who stops gaining XP. Changing classes means keeping your ability scores, race, HP, and whatever moves you and the GM agree are core to who your character is. You lose all other class moves, replacing them with the starting moves of your new class.
