I remember these being in discussion on the old forums, just wondering if they ever got answered.
1) Recouperating
The book seems to suggest that you can heal yourself outside of a city by paying 50 gold. This is the only action you can take outside of a city except for exploring dungeons. Is this correct?
2) Cities under Seige
I believe that you can still visit a seiged city as normal (ie. use its markets, temples, etc) and you don't have to fight the lieutenant on the city to do so. Similarly, if you choose not to fight a lieutenant on a space, the Overlord cannot "force" the encounter, he has to wait until his turn if he wants to attack you.
