1. How does the range penalty work for half-range creatures? If they're shooting past some distance then they do half damage?
2. I think I must be missing something. If I'm on a battlefield with no obstacles, it sounds like Archery III just turns half-range creatures into full-range creatures. So, there's not much point in getting Archery III as e.g. Haven, where the only ranged troops are full-range. What am I missing?
3. Does Archery III cause ranged troops to ignore obstacle penalties?
