Shriekwing is a two phase encounter which requires players to utilize line of sight to counteract some of the mechanics that this boss sends their way. The first phase has the raid fighting the boss head on, while Phase Two has the entire raid hiding from the boss at all times while dodging her ever-searching sonic rings!
