Shadows of the Dead can be Desecrated into a massive horde of Health Orbs. This build attempts to abuse that as much as possible while subsuming an ability that fits with the low duration.
Fire Blast is chosen because it doesn't need any duration to strip armor and fits with the rest of the stats. Pull is another good choice against unarmored enemies but requires an augment to make use of pulling health orbs and other items.
Duration is intentionally lowered to allow Shadows to quickly die after casting them. It isn't entirely necessary but there isn't any
[Corrosive Projection] synergizes with Fire Blast and Terrify to completely cripple armor. It can be switched out for an appropriate aura to fit the mission.
[Enemy Radar] mods help you and your team to track down enemies. They can be swapped out to suit your playstyle.
[Augur Reach] is a flex mod that can be replaced with any of the augur set mods as you see fit. If you don't want to make use of the Augur Set it can be replaced with whatever you want to use.
Arcane [Guardian] significantly increases your survivability against general content. It can be replaced with any other arcane to suit your playstyle.
