Spark of Reality got buffed pretty hard in the latest patch and I wanted to try a DW Warlock using this item. The only warlock build I could find using the Rah’Zin set was from @eardianm. Here’s my shot at the same concept.
With permanent buffs, Hungering Void, Mirror and Arcane Will

Didn’t bother to try Crucible, aoe is bad anyway.
Gear
Everything is BiS (I think). Relic is debatable, but I went for Eldritch Pact over Agrivix’s Malice mostly for flat chaos and hp. Crafted helm for stun resistance.
Devotions
Due to the new modifiers to Mirror of Ereoctes on Spark of Reality, I went with Hourglass instead of Abomination, was able to fit Ghoul and still had 3 leftover points for Wendigo. Result is lower dps than @eardianm’s version, but also much sturdier.
Conclusion
High single target dps (it’s Rah’Zin after all), lowish armor/hp/DA are (almost) fixed by the classic Hourglass+Mirror combo. Lack of aoe damage makes Shattered Realm kinda hard but, apart from that, I’d say this is a decent build, for a melee Warlock.
