PC on a gold Shadow Bow

Sundering Shadow Bow of Fortitude

Piercing Damage 15-28(req.12)
Damage +15%(while enchanted)
Armor Penetration 10% (10%)
Health +30

Thanks in advance.

Bump, in addition to needing a PC on an item I just got:

Chaos Axe of Defense
6-28 (req. 9)
Damage +18% (below 50% health)
Armor +5

I'm wondering if it would be worth it to change mods, so if I could get a PC on that and if I replaced it with a perfect furious and fortitude mod.

shadow - either mod is worth more then the bow
chaos - 3-5k

agreed, enchant bows arent worth too much.

salvage shadow, chaos no more then 5k
