You captured the theme of this year in a really interesting way! I Like the idea of placing haunts through keeping your warriors in a specific spot as long as they are there.
I think VP are scored whenever enemy warriors are moved from a clearing with a haunt? But I can only see that VP are scored when YOU take a specific action to force them, are they able to leave on their own and you DONT score VP?
If you wanted to battle an opponents building but a haunt is placed on it, are YOU able to battle that building? Does the haunt get removed along with the building? Or is the building kind of immortal as long as a haunt is on it?
Just some questions I thought were fun :) of course these fun questions are here because of the cool mechanics you've cooked!
