Descent into Torment

This is an Act 2 side quest offered by Kalderos outside the entrance of the Steps of Torment in the Broken Hills.

Objectives

 * Slay Grand Priest Zarthuzellan (0/1)
 * Speak to Kalderos in the Steps of Torment

Guide
Grand Priest Zarthuzellan is located in his room toward the north-east end of Misery, the third level of the Steps of Torment. The portcullis at the bridge to his room will lock behind you until he is defeated.

Kalderos will be waiting in the room by the Gates of Anguish. Speak to him to receive your reward.

Reward
The Skeleton Key will allow you to unlock the Gates of Anguish, which lead to the fourth and fifth levels of the Steps of Torment (Suffering and Anguish). On unlocking the door the key will be used up and another must be crafted with the blueprint to enter again.
