Hey, Im currently at the quest "Dread Purification" where i should complete the "Essence of Anguish" and it says it should be displayed in my quest tab. The issue is, that i dont have it. I have done some research and it should be obtained by defeating Omnigul in the mission "Ghosts of Our Past". I have done this mission but didnt get the essence. How do i proceed? Cant redo the mission, been down to the keep again but shes not there, any other way to obtain it?
