I'm loving this game! Such a gem. I have some questions I couldn't find answers to in the manual:

1) Do rough terrain types affect your damage when attacking?

I know Light Infantry and Skirmishers get bonus damage when standing on rough terrain, but for example if your archers attack an enemy unit that is in a Forest tile, do they do less damage compared to if the enemy were on an open field?

2) Where can I find information if the unit is in a Closed or Open formation? I see formations mentioned in the manual but didn't see where I can check that information in the game.

3) Do units get any sort of defense bonus if they are in castles, towns, keeps etc?

1) There is a whooooole page of game tips in the manual. You will like having read those -:)
imo, archers are never affected by terrain, but skirmishers get a bonus on rough. Cavalry get malus i believe although it is said ambigously in the manual.

2) Unit tables in the appendix

3) I think so. Cant flee anyway.
