If you are headed to the undead Jailers room, Marked #2 on Karnors Castle Catacombs Map from EQ Atlas. Stop at the door and face away from it, toward the stairs. Directly in front of you will spawn, ironically, a construct. The ring is a ground spawn beneath him. It will look like a bag.
Remember to turn in the Greyed Tome with the Ring of Construct to Master Niska in East Cabilis.
The Resulting text :
Master Niska smiles at your dedication to Cazic Thule and hands you a small gem.
You gain experience!!
Anyone getting this far Gratz on your Mark of Clarity ;)
