PC on shadow shield ASAP plz

I found this nice shadow shield and was wondering what it is worth so I won't sell it to cheap!

help me out plz!

the shield:
req9 max armor shadow shield
with -2dmg in stance +7armor vs piercing dmg

I thought I have read people needing shields like this for FoW solo but I'm not sure, enlighten me^^

hmm yeah something called the spider run, they normally want +8 Vs and -3 hexed I think tho, but -2 stance would be good probably...15-20k to a spider farmer imo.

10-40k or so^^
