This is much easier than it sounds. Head north from Scarwood Ridge and you will see an Air rift on the left of the path with a statue-thing in the middle. Naga's and large birds surround it. We suggest you head up the hillside till you find a spot behind it that seems "thinner". Pick a mob and use the ray. It will toss them to the reliquary and back to the Plane of Air. Pick carefully and clear a path to the middle, then click the reliquary to seal it!
The ray does NOT vanish when you toss the sixth mob so don't worry you will lose your weapon this time.
