This just happened yesterday; I was in world 9 fletching in seers, a person with a skull and poison comes in with extremely low health. He drinks an anti poison and leaves. then about 5 minutes later, full rune, and obby cape, a glory [4], a ring of wealth, and some other stuff appear on the ground. I got the items above and full black d'hide. I don't even know what happened... Oh well, free 700k for me!
