Yep, I won the roll on this one last night, didn't seem to be a tough fight, Dark Blue mob to a lvl 70. Think this dropped from a named though, will update once I get with group members to verify. Shame it's just a range item, my bow is always equiped so for it to be usuable to me as a ranger, I'll be swapping it back and forth, kinda of a pain. Happy hunting!
I got this to drop from "a barbarian" in the Devastation on the second or third day of the expansion. It was soloable and fairly easy. So either this is just an extraordinarily rare drop, or an itemization bug.
