Amazing, thank you!
I have some additional questions after playing a little more if I may:
1) are the +1 for the blacksmith cumulative? eg. can I spend 2 tools for a +4 on the control check?
2) can I build multiple tools with 1 action? Or just 1 tool per action?
3) Do failed investigations leave a mark (for the two investigations per hex rule) or only successful ones?
Thanks!
