PC on Shadow Axe

Sundering Shadow Axe of Shelter
Slashing Dmg: 6-28 (req. 9 axe mastery)
Armor penetration: +20% (Chance: 20%)
Armor +7: (vs. Physical Damage)
Inscription: "Strength and Honor"
Damage +15%(while Health is above 50%)

I'd first salvage for mods, axe itself 15k~

Agreed. Salvage sundering mod out and then just try to sell the axe with the remaining stats if it doesn't break (the 15^50 and +7 phyiscal aren't worth the risk of destroying the axe after that).
