I have that super fast ranger bow, quill rain of it linked with explosive arrows and a burning gem i thing, its a real good fast way to level a ranger, i have like 6 70+ characters or so with a bank full of shit, if you need any gems let me know, or items for that matter

pretty fun bow build, this is with marauder but still effective, thats the quill rain
