What is the building time for C20 and above
Hello!
Unfortunately, there is no publicly available information about construction times, without boosts. Therefore, we record these times using one in-game city that has 0% “Building Speed Bonus” (No Officers, nothing developed in the Academy and no Alliance). But it takes a time 🙂
Sooner or later we will have building times for c20+.
Thanks for the question!
You have a type-o on lv26 steel requirement.
Fixed, thanks 😉
What does the two level requirements mean when you can’t upgrade something
Ex:
Main Hall Lvl 8 / Lvl 10
Hello!
This means that you want to upgrade a building that can only be upgraded if the Main Hall is Level 10, however in this case your Main Hall is only Level 8.
