Zodiac Bow: No inherent mod which renders it useless, Merchant/salvage
Shadow Bow: Unwanted nonmax mod and high req, Merchant/salvage
Zodiac Daggers: Again, no inherent mod, Merchant/salvage
Composite Bow: It's not max, but I've acctually never seen +14% - 1 Health regeneration before, might be something super-rare or it's merchant food (get 2:nd opinions)
