And if it was it would be the most absurdly broken sienna in the game (there are a few blacks easier to reach than the second pile of bones). The first pile is about right for a sienna. I've had this one a few times. If you spend enough time wandering around the wastes it eventually resets so it's probably there somewhere but walking over both (empty) piles of bones triggers it, and whatever did trigger it wasn't an obvious or semi-obvious pile of bones.

I've had many other players vent their frustration to me over this spot, and nobody I've ever heard of has ever successfully gathered it. Now that Hardan woods is gone it's the only wand spot left that I can't find.

If you land this spot your recourses are limited wands, committing to a long time wandering the wastes and hoping you walk past it, or doing without shield (no big deal for most mage classes).
