Bosses in order
The story bosses fall in this order: Shrine Guardian, Dagoom the Sea King, the Necronomicon, Poenir and Duenir, Josami Lord Saijha, then Queen Siraatsu. The Gigantic Serf, Herald of Okbujo, Blood Angel Lords and the dragons Usunha and Wujomiod are optional but carry boss achievements. Nothing saves automatically, so save at the Crystal Monument before each door.
