1st) Can you buy more than one treachery per game week as an overlord? It doens't mention it everywhere. I mean does buying 2 points of treachery counts as 2 upgrades or one?
2nd) Surges given by skills like prodigy etc are they black dices or do you count them as 2 boosts (either extra dices or boosts)
3rd) 2 lieutenats in a city will they produce 2 siege tokens? The rules that each one will produce one but does it work that way?
4th) Let's say a lieutenant is sieging a town. Heroes move on the city are they forced to attack him? Or they can ignore him and visit the city instead?
