I now understand what you mean by the roll over question. I dont think I clarify in the guide (my bad), I run Target Numbers and Defense as "meets it beats it" for the total of the check plus bonuses.
🤦♂️ I was reading from an old draft on my phone. In the case of "meet or exceed TN" that is specified on page 14, the More About Defense section for the current version available.
And thank you for checking out the game! Feel free to share thoughts after playing sessions, I'm always eager to see what people do.
