Visit command is used for dodging incoming attacks. It allows you to send your troops on a 'visit' to any villa, not doing any damage, nor supporting the villa. It acts in the same way as an attack apart from the not doing any damage; instead the eat cookies and drink beer. It's just the same as the attack breaks that are activated at christmas/new year, you get the same kind of report, but you can switch between Attack and Visit whenever you like. It's an easter egg that even most IGMods don't know about. I could explain it, but it's a lengthy process, and seeing as so few people know how to do it, my instructions don't come cheap.
