This is usually around 1.5k-3k on torv, a few higher ones, I was lucky enough to get one of these from a guildie, very nice, well, it will be in 20 levels =X
Unfortunately I have seen this item selling on Xev recently for around 500pp if you can believe that. But our server is only of the older ones so everything becomes junk to the ubers after a shore time.
For the record, the mobs that drop these are rediculously overpowered. I'm a 55 mage and one of these by itself whipped my pets *** and was on it's way to do the same to me, before I gated the hell out of there. The fact that every mob in the zone gets that weird poison spell makes it even worse. Just a head's up for people who are looking to slaughter Murkgliderrs for these.
Dunno about the Povar server, but on XEV the Obulus Death Shroud sells for 10-15k. I could see this easily going for a lot more than that. Same Mana Pres III, and far better stats.
