This is the second time in a row that Tormented Duriel is stuck underground and I can’t kill him. At this point, the summoning material cost is lost and I’m stuck in Duriel’s cave. In this case, I have to exit the game and enter again. In this case, the resources used for the summoning are lost, as well as the several hours of time spent to obtain them. I request the developers to fix the bug and provide compensation.
