The Embassy is where you accept reinforcements from Alliance members in the event your city or subordinate cities are attacked. The Embassy can be built at Keep level 9. To maximize aid from alliance members, this building should be kept upgraded to the keep level if possible. The Market must always be upgraded before upgrading the Embassy.
Upgrade Requirements[]
You can build the Embassy at Keep level 9. All upgrades require Keep and Market to be upgraded first. Upgrade time depends on your Monarch gear (Strength Crown) and your construction research.
