PC on Gold Sundering Warhammer

Just wondering whether to sell this or salvage and hope for the best.
Thx in advance.

Sundering Warhammer Of Warding (Gold)
Blunt Dmg: 19-35 (req 8 HM)
Dmg +20% While hp is below 50%
Armor Penetration +20% (20% chance)
Armor +7 (vs elemental attacks)

Tried to put up a pic but couldn't get imageshack to work.

Skin?

Is it spikey, club-like or the same as the pvp skin?

Same As PvP version I suppose, has a little gold circle on the head.

salvage and hope
