Clan Wars – new faction mechanics.

Added the racial ability "Night Scouts": at the beginning of the day, a Ranger hero discovers neutral armies on the map within a certain radius, if he has already fought similar creatures (as part of neutral armies). The ability is activated when the Ranger Guild is built, and its effectiveness depends on the Avenger skill and the presence of the Ranger Brotherhood. The idea is that "Night Scouts" and "Sworn Enemy" should work together to create synergy.

The word "synergy" is probably a very trendy word, since you used it.
There's no synergy here. It doesn't smell like anything good...

Let me explain:
1. Sworn Enemies are needed for breaking through defenses. So, there's a good stack guarding something, and what do you do if you haven't killed any of those creatures yet? NOTHING. Your "synergy" doesn't work. If you have killed them, then - hooray, go to the city to change your Sworn Enemies. Powerful. Then come back and kill. 2. It wasn't possible to generate creatures of the same faction as the enemy on the map. You didn't kill them to get the double growth bonus. You didn't go to the city and set up the necessary Sworn Enemies. The racial ability doesn't work. What kind of synergy are you talking about?
