If you ask me, anyone would want a macer sampire with 120 resisting spells so I dont understand why ppl won't bid.
For the right buyer that jewel could be 350 mil, easily.
I also have a 10 mods and 35 skill jewel, very solid, for tamer archer and I got **** offers for it too. So if you ask me, I wouldn't sell it. Both yours and mine, they are the same jewels than 3 years ago and they don't look like they are going to lose worth any time soon, further more with multiboxers ban/prohibition.
So if you don't need the money, put it in a chest at home and wait. It will eventually sell for the right price.
Regards.
