A third pamphlet, with extra stuff (like runes, arcane tools, and additional rules for the final battle) is on my to-do list, but I'm not sure when I will be able to complete it. I hope before the end of the year.
Rule Suggestion
It's annoying when a PC die in the begging in a oneshot. He can make another hunter or wait for the end.
So, you could add a rule to let him come back.
Example:
The PC who died will return to the Workshop if he has at least one insight. He will loose all insight then and must wait the current scene end.
The PC who died will turn into a corrupted hunter if he has no insight. He will now fight against the other PCs.
Ah, the corrupted hunter is an interesting idea. However, I'm not sure it can fit in every game - it's more a matter of taste. So, I agree there is room for a rule about the character's death, but I think we need a more "generic one," and if some players are happy with the idea of having a corrupted hunter, they have my blessing!
