This build focuses on Power Duration ([Narrow Minded], [Constitution], [Augur Message], and [Primed Continuity]), which affects the longevity of Shooting Gallery and Shatter Shield, which empowers damage and CC enemies, and gives up to 95% damage reduction, respectively.

I only use [Augur Secrets] since Shatter Shield reaches 95% reduction at 120% strength, and since I use Gallery more as a CC than a damage boost, additional 24% strength is enough for me.

I use The [Energy Siphon] and [Primed Flow], since I am gas guzzler in terms of ability usage, and [Vitality] to compliment Shatter Shield. Those three mentioned mods can be changed to whatever mods fit your style.

Finally, [Stretch] and [Cunning Drift] as my Exilus, to counteract [Narrow Minded].
