You need 36.67% CDR then use the numlock trick. But get it on your rings/quiver/shoulders. I don't recommend gloves because you will give up a high roll on vit. Try to get a Crit/Crit/CDR ring. I'd keep the Vit on the bow. It's tempting to roll for more RCR, but I would roll more weapon damage. The grind is getting collecting mats to use the cube. I don't think this is a great bow to push solo GRs, but, it'd be good for farming.
