Welcome to the Wet Circle... yes you read that right. This is one unique sweat circle where the Screecher is surrounded by water. Once its dry and drowned (or killed) a new one will spawn. Polite notice, if you see someone/a group sweating DO NOT kill the Screecher unless it is dry and you have permission to do so.
Missions that can be found here
Daily Sweat for Ticket
Collect 500 bottles of sweat. (Seems atm that its 500 successful pulls of sweat and can also be done by looting sweat while crafting.) Hand in 500 sweat to the bottle
