The Rally Spot in Evony Age 2 is one of the main buildings in this game along with the Barrack, The Wall and the Relief Station.
The level of your Rally Spot decides how many attacks (waves) can you send at one time along with how many troops can be sent per wave.
The below table has the basic information on the Rally Spot:
* M.S. = Michelangelo Script
Exercise: This is an option available within the Rally Spot to play out a mock battle to check win/loss and troop losses BEFORE you march your troops out. Although this is not very accurate, the option will give some idea about battle sequence to new players.
March: This will allow you to enter coord of your target and send troops directly. This option is helpful when you have a city marked under Coord List and is available under the favourite list.
Medical Camp: This is where all your wounded troops are kept. You should heal them as soon as possible otherwise they will slowly die. Healing costs gold. The Auto Heal option allows you to automatically heal troops but it costs 4 times the gold. You should enable auto heal only when you log off from Evony so that your troops can heal if your city is attacked while you are away.
The check box of “Open Gates to fight” is very important and will decide the outcome of a battle. If this option is unchecked, you troops will not take part in the battle if you are attacked. Only the Wall and its fortifications will be used as defence. You troops are safe. However, even an army much smaller than you can defeat you if your gates are closed. Also, your Alliance members cannot reinforce you if the city gates are closed.
If you have a fairly decent army depending on the age of the server, you should have your gates open. This will allow your troops to participate in defence and also engage enemy scouts (provided you have scouts).
