I did the level 35 Prison of Elders run through and finally killed Skolas after many attempts. In the treasure room, I got the etheric light and both an armor core and weapon core. But the Skolas specific rewards did not drop. I didn't get the Hildan Seeker ship, the Queen's Web shader, or the Kellbreaker emblem. This is the first time I have killed Skolas. Is there someway I could get these rewards?
