Join this group and keep the chat open: Rook alerts. Don't panic if you are in an attack. Nothing bad will happen, even if it goes on for hours (we had that situation shortly after the reset when few people knew the skills necessary to fight the Rook). Nowadays the attacks only last for a few minutes before they are over with. The word gets out fast and the Rook is very easy to defeat once you have around 10 people there (which presents no challenge).
