I know the final book is still being written and the Quickstart Rules may change before publication, but the game is already easily playable, despite this advancement rule that is common is several playbooks:
In various playbooks, under Advancement:
advance 3 basic moves
The Fae, under End Move:
... or advance persuade an NPC
But the quickstart never says what is Advancing a move or how it works. Even making it look like an incorrect or imcomplete rule.
Is it to get a bonus when rolling for that move? Or a +1 to its related Stat? Where do we write which move is advanced on the playbook?
