Ah okay. So you write a number in there, that's the obvious part I was missing. As opposed to "fill in as many boxes as you have Knowstones", which is basically everything else on the sheet.And then it makes sense. Thanks for the clarification!
No problem,
I’ll try to improve the wording on the campaign sheet so this is more clear. Currently, from the back panel:
KNOWSTONE LOG
Record the number o f Knowstones collected at the end of each run. Use this total to assign Knowstones to Abilities or Mastery tracks.
