Its supposed to be a number of dice equal to your attribute score. I got it right when writing the rule under "Choosing Attributes and Grimoire Cards", but thanks for catching my embarrassing typo under that section. I was knee deep in college classes trying to get this game done before the game jam deadline, so I hope the game still plays smoothly. Thank you for letting me know about this and I hope you playing it!
