This is a simple and straight-forward build. You just puton your right-click, use it and never take your finger off it.
You can play without any unique - But I would strongly advise you to getboots. They just give you way to much survivability (1000-6000 ward) making you almost impossible to one-shot. You don't need them while leveling but they should be acquired as soon as possible.
You're a map-killer and a boss-shredder at the same time. Try to shoot enemies from far away on maps and let them come to you. The closer you are to the enemies, the more damage you do. Against bosses, you should just put yourself on top of them and right-click to death. You should get 4000+ ward every second, and they shouldn't be able to one-shot you until 500+ corruption.
I was made aware recently that this build has the possibility to shoot really fast because of a known bug. This should still be 100% viable at 1.0 launch because they should also fix the bug that makes thearrows go thru enemies, balancing the two.
I'll update this on 1.0 release depending on the situation.
