Just want to be first who published this build I created yesterday :). It is new 2.3 Helltooth build so keep in mind that some skills here dont reflect the PTR state!! I will updating this because it is still in test phase!!
Wall of zombies--->Wall of death (poison rune)
Spiritual Attunement will regenarate more mana due to changes on helltoot set and with new 1H spear, this passive will be no more uses, because new 1H spear reduce cost of Zombie charge and BBV will be enough to management mana. Also, no
in weapon slot but new weapon will be better choice Furnace
Physical Attunement will be much better than now and this build is close range, so why not :).
So, you simply cast Wall of death, then BBV to same area (We have FS because of belt and FS will reduce CD of BBV quickly) and Piranhado in the middle of Wall of Death and Horrify (tiky helm) then simply spam bears! Your Obsidian ring reduces CD of Horrify,Piranadho and Wall of death very quickly, so you van spam all these skills in nice rotation :). Helltooth full set bonus boost Wall of death, Piranadho and Bears, BBV boost all and gives you mana, Tiki for CC, Piranhado for CC and more DMG boost, FS for BBV CD and single target (MoJ will help with single target dmg)!!
