So a group of us went in tonight to finish our stories and we got to the part where Zhaitan has his tail shot off and clings to the side of the rock. At this point, we had endless waves of risen spawn, they would not stop. We would go up to try and kill the eyes and it would be instant death. We tried to pull back and dwindle down the numbers but they just kept spawning, after about 20-30 minutes and 50 silver in repair costs we just gave up. Is this how the fight is intended to work?
