Every 4 seconds, 20 Gold is given to the player who controls the tower. When you control the tower and have researched either Tower Spawn level 1 or 2 a ghostly unit will spawn. This unit will respawn from the tower 30 seconds (except a Charrog ghost which spawns less frequently due to higher health) after he dies and will continue to do so until the game has ended or the player loses tower control.
Tower Spawn is an upgrade available to every Empire. It will spawn a ghostly unit that you cannot control that will attack the enemy directly. Ghostly units do not cost population.
