PC on Fellblade

Just wondering what my blade would be worth:

15-21 Req 10
Sundering20%/19% chance
Armour +5

Thanks.

merchant, or salvage the 20/19 and +5

Salvage for 20/19 yes

how much are the mods worth themselves?
because i have another sundering with 18% chance, and i'm willing to sell the 19% if its somewhat valuable.

19% probably worth about 5k or so
i wouldn't recommend wasting ur time on the 18% though
