Double Adrenaline on hit (Chance: 10%)
Health +29

To be honest, I just put this together out of gear I had tucked away, it's customised, and a mate wants to know how much it's worth, so thanks for any help.

(EDIT: Sorry about the damage, I was in abit of a rush... *ahem*)

11-22 damage?

~15-20k

Cool, thanks.
