Maybe an expensive bow?

I'm wondering how much this is worth. I cant find anything else like it, any help would be appreciated.

EDIT - Just want to let you know some guy told me to exalt slam it so I did and in your reply guess which mod I got with it. If you guess right I'll send you some good old life energy.

Its worth maybe 2 exalts? I checked on poe.trade and that 2 level of socketed bow gems mod is not very expensive. I don't know about onslaught on kill but I don't think it overshadows the weak physical damage and lack of attack speed.

More like 1 exalt just for base to scour it
