Could i solo zakum properly?

I could solo zakum pretty easily at 13x, you shouldn't have a problem, just do it in the early hours of the day. It takes a bit longer post BB thansk to avoid getting nerfed but arms go quick with upper stab. As for body, just be careful with Final Cut. Use the summons to FC away from the body so you dont get insta killed. Takes me around 30-40 mins total with witch brews at 36k range, I'd predict you can do it in little over an hour. Pack lots of pots and good luck!
