Reservation Tool

What is the Reservation Tool?

The reservation tool was a player-driven development that was introduced into the game in December 2012. It allows members of an alliance to ‘claim’ a city, showing their alliance-mates (and the members of alliances that have access to your alliance's reservations*) that they have the intention of conquering the city. Please note that reserving a city does not prevent other players (even those from your alliance) from conquering said city. It only shows them that you are planning on taking it.
(*)This doesn't have to be alliances that you are pacted with.
