Although this collectible is close to the main road, it can be easily missed as you run by. What makes it so well hidden are boulders as tall as trees that surround it.
East of this location, at the start of a dirt road, you can find Dringoth (skull on ground). It starts an awesome quest “Keeper of Bones” that is part of Bone Orchard Objective. This is one of those quests you’ll remember down the line and that enhance the game experience.
