Well, we’ve reached the point where I’m out of ideas. Perhaps I’m missing something? Lille could stick around and try to learn the habits of these things; figure out their likes and dislikes to repel them or draw them into a trap, then figure out how to destroy them. But even just some of that trial and error would take quite a long time. As much as she wants to solve this problem, she definitely doesn’t want the group to leave without her.
One option is to warn some of the locals who tend the fields and orchards, and hope for the best. Another is to go ask the help of the adventurers. The first one is near to giving up on the problem - would they really have any better chance of solving it? The second is quite the opposite of what Lille wanted; she was going to prove herself useful to the group to help in their tasks, not ask them to help her solve a new and separate problem with no clear personal gain. It is not in her character to step away without saying anything, so those are the two options I can see.
This has definitely been more involved than I expected. One of the aspects I enjoy most about this kind of gaming is the cooperative element. While each character still needs to take their own actions, make their own decisions, and sometimes work independently, the group strengths can help make up for all our various deficiencies, both as characters and players. If I’d known that delaying in joining would mean this kind of solo problem solving, I might have chosen differently.
So is everyone ok with Lille joining now? Or is there some other way for her to reap the benefit of that very high roll? She’ll suffer the no-hunting penalty for the low roll either way. Also open to other ideas if anyone has them :)
