PC: +30 Health, 10/9 Sundering Hammer

Wondering how much a hammer such as this would go for.

"Gold" Foehammer
19-35 (req. 9)
+15% damage (in stance)
Armor penetration 10% (9% chance)
Health +30

I am likely going to keep it, but it is still sort of up in the air at the moment so I wanted to find out what I could fetch.

darn, 15% in stance. Not sure but i bet if people buy this it will be for the fortitude or the sundering

Yeah, wish it was an "above 50%" damage add. But I do find myself almost constantly using stances, which is why I may keep the hammer. My current sword is nothing great, so I may make the switch to hammers and use this weapon. I will have to see if I will use the stances as much using a hammer before I decide. I dunno, maybe I will just keep looking for a new sword and board.

Any ideas on value?

PS. A little off topic, but what are the most beneficial stances you all use? (I know it depends on situation, but just a general comment)
