I was doing the urgoz mission aft i got a ferry and while doing it i found what seems to be a good rare skin hammer that ive never heard of and i was wondering how much i could get for it

Furious Gavel of the Nephilim of Defense
Blunt Dmg 19-35 (reqs 9 hammer mastery)
Dmg +15% (while in stance)
Double adren on hit (chance 10%
Armor +5

thanx in advance

tell me if i was right about it being a rare skin
