When attacking enemy cities, the first thing you want to know is “Is it a dead account?” or “Isn’t it a city that has been burnt and no soldiers?”.

Here, we introduce the results of an actual survey on the power value of a city that has already died and that of a city that is still alive.

Monarch Power of the Dead City (Rough)

Note:- About gray zones
Power values tend to be proportional not only to the keep level but also to the monarch level. Therefore, there are gray zones that cannot be determined only by the keep level. For example, even if the keep level is low, if the monarch level is high, the power value may be high even though the city is dead. (It can be said that the monarch level equals playing time. If the playing time is long, the basic power value is high because the research and construction in the city is often satisfactory.)
