pc: zealous long bow of shelter (purple)

Hello, I was wondering if anyone had an idea how much this bow is worth. Its damage is 15-28, only a 6 markmanship requirement. +14 damage while health is below 50%. zealous; +1 energy, -1 energy, +5 vs physical attacks.

Thank you !

anyone have any idea? I am still kind of new and any help would be greatly appreciated.
