I looted a Lost Lambent Stone from a caravan chest in the river by Cazic Thule. Approx. location is -1245, -830.
"You pry open the chest mired in the bottom of the river bed. A shrieking flash of light and a rush of bubbles burst past you towards the surface."
Opening the chest spawned a cursed guardian. 112 critical hit killed it, looted the Lost Lambent Stone from the chest, mob had nothing.
