Yep. Attacks keep going on until somebody stumbles onto it and shouts in Rook Alerts.
Rook Rolls: 1/12 chance of rolling Rook. Furthermore, another chance for the Rook to actually grace you with his presence; 1/2 chance I believe. So 1/24 chance of Rook Attack from roll. In a rolled attack, just some rooks fly about and trees and animals are berooked. If you hit that 1/12 chance of getting Rook, either way, roller gets -50 mood. If the Rook comes, red lights and giant words. Also theorizing there are different types of Rook Attacks (different images and rook formations) and a further chance for those after the 1/2 thing.
Has anyone actually seen animals die from this? I've seen trees die, but not animals. It takes a VERY long time for this to happen, so no need to panic if you see an attack.
yeah--- i've seen some aftermath of rook attacks that noone fights, as long as people stumble upon it, you can usually revive all the animals and trees as long as you have 2 people :)
