PoE ThisIsMyFloor builds

Got 4 arrows +2 from Dying Sun (and mirage archer +2) I can do all the bosses but I think I can't do any ubers, damage is not insane and I am not so good. I maybe got about 3-10 million dps if they stand still. Is there anything I have overlooked or something I can change for more effectiveness? I got sockets and links to spare.

I think that's the way to link. Had this on my pob when checking for damage. Don't know if I changed anything since Forgot to mention staff mastery 30% inc defenses is huge. 14% life as es on chest. Leech from the cluster jewel as well as es leech from elemental mastery I believe. It ain't huge but it's still sweeeet. Since channeling can be dangerous I also said 5 hits per second like a dumbo. It's a lot more but I am too dumb to do quick maths. 20-25 balls each hitting every 0.4 seconds.
