I think I'll let the other player modify what's necessary, I might be unavailable for the next 5-7 hours.
My plan is, if the team, regardless of the intel, decides to ambush, the succubus will be guiding the good-folks to the most convenient place for attack. So there are TRICK rolls for:
1. Misguiding the goodfolks to follow
2. For each goodfolks member, misguide them to scatter (Defense Against Caught Lying if fail)
All to make the situation for any SKULK more advantageous.
Is this possible based on the system?
Regardless of the dungeon style, we might need to review this.
