To receive this quest you should go to the Decrepit Ruins and talk to Magister Sang.
We found an ancient armoury being looted by Magisters. However, when they tried to breach an inner door, they found it to cursed, causing several of them to die. If we can figure out a way past the door, then we might find something powerful hidden past it.
We learned that the Magisters have been taking Purging Wands dating from the time of Braccus Rex from the armouries and caches scattered around the island. Perhaps they overlooked some.
Cast Bless on Guardian Lever then use it.
We managed to open the door leading to the second room.
Come near Corrupted Tyrant's Helm.
We found a strange monolith in the second room.
Open the shrine. You need a Source Point to do it. Inside you will find Corrupted Tyrant's Helm.
Using Source power, we activated the monolith.
We left the island behind, without having discovered the secrets of this strange armoury.
