Spy
Spies are a troop trained in a Garrison
Description
The Spies are unassuming lot whose psychic abilities help them travel, unnoticed and gather intelligence on the enemy telepathically. They move swiftly, like ghosts in the wind.
Use
Spies are the troop you will send out if you want to collect intel on another player. They can only be defeated by other spies when sent as a Spy march. Although, they can also be sent as an attack the same as any other troop can, but their speed is made more or less useless for normal attack by their lack of load capacity.
When sending these troops as spies, to collect information, you do not require a general and they may only be defeated if other spies are defending the City. However, if they are sent as part of an attack, they may be killed by any troop defending the City, including the Great Dragon.
