Depends on the clan. The average would be 5 to 7 hours. The leathered wings take a while to get rid of, and they regen.
Build more buildings. Beef. As far as I know, the EE wars aren't going to end for a long time. When are the Chaos wars going to end and Season 3 will start? Sometime in early-mid January. Check the developers news posts.
Bear: A hansel is a build where almost all buildings are spy, except one or two attack buildings. To become one, just build a lot of spy buildings.
Are pure spies used in EE wars? How desirable of a build are they compared to hansels in wars? Do they need ADT if they are used in war even though there are no troop buildings? Is 1.5m SDT still a requirement for a pure spy? I realize I have asked 4 questions. Thanks in advance for any information. I started the game in the middle of the last war season and didn't participate and would like to try the upcoming season.
Pure spies have been used by clans in EE wars, with varying degrees of success. They do not need ADT because if used correctly, they are never stolen from.
I'd say hansels are easier to be, so therefore are more desirable, and I do not know the 4th question about SDT
