I mentioned this build to
Kythik
, of course I said the magic words, movement speed, and he was interested. You can get close to 300% increased movement speed while mapping. The basic idea is to take a BV autobomber and integrate Elusive and Badge of the Brotherhood.
That's my "take" on the build in the video. It doesn't stray too far from it, I tweaked the reservations a bit. Honestly, making my own PoB is just conducive towards learning the build, even if you end up at the same place. It let's you learn what knobs can be turned instead of just copying exactly what the build guide says to do.
For instance, I don't think reserving Zealotry is all that important unless you plan on doing a lot of endgame bossing. Picking up Flesh and Stone, Discipline, and MoM help the survivability a ton. Additionally, with some further investment like a L4 Enlighten, expensive Circle of Fear, and a delve ring for cold leech, you can drop the Onslaught on HoI and Atziri's flask, replacing them respectively with Ice Bite and Cinderswallow. There's a lot of ways pouring extra exalts into this build will produce meaningful results. Even a Farrul's Fur would be useful if you're bossing.
