PC on a Shadow Axe

Req. 10 Shadow Axe inscribable
15% while enchanted
+30 hp
Furious 10%

Btw, what's the price of a perfect req. 10 Fellblade? I got one with 33% crippling, +5 armor, inscribable. Is it worth of buying perfect Sundering and Fortitude upgrades and selling it?

Also, what's the price of Ancient Armor Remnants?

Thanks

Shadow axe - salvage +30hp mod and sell for 6-7k, then try sell axe for another 7-8k.
Fellblade - ~30k, don't mod if you intend to sell.
