Hello, To help set up the boss notification system in game firstly open your menu and go to the Adventure tab in there will be the boss notification system to help set up in game notifications up to 30 mins prior to the boss spawning. You can set it as you like to give your extra notifications as it gets closer to the boss spawning. Hope this is what you were looking for Regards, Ishgard
