[3.2] Spectral Spirits >Occultist Summoner<

The premise is rather simple: Use a 6 socket bow with Essence of Insanity Spectral Spirits as your vessel to inflict Decay, then scaled your decay damage through supports and minion damage. This allows you to scale only minion damage, as spectral spirits never die. With that in mind, your best choice for single target becomes Summon Skeletons with poison supports. In order to scale both of your damage sources through curses, you resort to Despair for obvious reasons, Temporal Chains for some defensive value as well as extended poison duration, and Poacher's Mark. Poacher's Mark may seem unusual, but the added accuracy contributes greatly to the stacking of poison considering the low hit rate of skeletons. It's relevant for your Spectral Spirit decay as well since this will allow them to gain frenzy charges, further buffing their damage. I planned on playing this build before the Occultist rework was announced, so the fact that minions can now trigger cursed monster explosions was a welcome surprise. The playstyle is rather simple: Just lazily walk around and let your spirits kill stuff for you. For bosses, drop a wither totem and spam skeletons ontop of your target.

The Covenant is required since your mana will be completely reserved by curses and discipline. You can just specc into "Whispers of Doom" until you get a +1 curse Sidhebreath. Occultist Wicked Ward + Soul Strike quiver make a good defensive option. You will need some minion speed, so drop one damage support on your bow for a Minion Speed Support gem until you craft some decent rings with movespeed. Minion Damage and Increased Life are all you will be needing on your jewels, use the spare mods to sort out your resistances and attributes.
