A Necessary Evil
One of the three subquests of the Shield or Blade sidequest in the Duat realm. This one requires you to search near the Apep Khat area
You're looking for the piles of dark scales, with blue particle effects streaming up from them.
They are all on the lower most T-junction level of the area- none are high on the walls or on the levels above. Collect all five to complete the mission.
