Embassy is a busy place: Diplomats from all over the world negotiate contracts here, forge treaties and found alliances. In order to get a larger alliance you need to upgrade your Embassy. Also, every level of your Embassy increases your diplomacy points.
All Embassies give 1 diplomacy point per level, except for Level 1 which gives 3 diplomacy points.
You are able to found an alliance with 3 diplomacy points ( not a Level 3 Embassy).
A player cannot remove the last Embassy built. After joining an alliance, one must maintain at least one Embassy. To move or remove an Embassy from one city, another must be built elsewhere first.
For more info on the usage of embassies: see
Alliance members that have the special ranks of
Leader, General, Home Secretary or Diplomat will have additional options in the small floating window.
Remember One ( 1) dump level counts as four ( 4) warehouse levels.
