PCs will initially start at level 1 and level after their first completed quest. From level 2 onward, PCs can level every 2 completed quests.
Once the game gets to higher levels, PCs can be created at (or leveled to) the recommended level for each adventure. Any players not comfortable creating a PC at the recommended level can ask to use one of the playable NPC character sheets.
Players are not required to play the same character every session. If you would like to try a different ancestry or class, you can either create an entirely different character at the level recommended for the session, or you can make changes to your current PC.
Note: Since there is no organized play system for Daggerheart, these guidelines are experimental and may change depending on how well they work.
