Some rule points of order:
- Not sure about the scan blocking. First of all, you should use the rule that you can't block the same person two nights in a row. Otherwise, some baddie spots the Seer and just blocks him continuously... which I just realised is stupid since he should just have the seer hunted... So I don't really see any situation where it'd get used.
- Does lowering the scan chance for a baddie also reduce his chances of finding the trait?
- Also, how does this interact with the nightly move order? What if two people try to block one another?
1. Solved it yourself ^^
2. Yes
3. If they block one another, both do not get to scan
