I have one and I'm willing to trade it for a price. If you are serious and want it the minimum price is:
20 Red Scales AND a Dun'Robar Ring (+7 Con, Stunning +10)
Hefty opening bid I know but since everyone and there brother wants a stone I figured if I'm willing to pay the TP points for it then I can ask for the moon.
Okay how this will work: You have the minimum bid. I'll leave this open until Friday 7pm EST (GMT -4) for people to decide if they want it and come up with the bid price. If I get a taker then its theirs. If multiple people want it we'll deal with sweetners at that point.
If you don't want to wait until Friday to own the stone...make me an even more outrageous offer and I'll trade it on the spot.
