Use the Aura helmet

Aura: Energy Siphon

Rank 4 Fleeting Expertise (it's important to leave it at 4, as efficiency caps at 75%, but higher levels further bring down the duration of Blessing)

Rank 4 Streamline (or maxed, but 50+25 is already 75, so whatever)

Max Continuity

Max Constitution

Max Narrow Minded

... Whatever else you feel like having, depending on how much forma you're willing to go through. With this build, Blessing costs 25 energy and has a duration of roughly 24 seconds. With a single energy siphon you'll recover about 14 energy throughout the duration of Blessing, with two energy siphons you'll get about 28, so without using any other skills you'll be able to constantly use Blessing. Of course you can also use Energy Vampire, though with those corrupted mods it acts kinda weird (short range, long duration between pulses). And there's still energy orbs, to even further boost your energy pool.

Personally, I fill those 5 spare spots with Link, Energy Vampire, Rush, Focus (for boosting the energy from Energy Vampire), and Enemy Sense. No need for defensive mods, as you'll be invincible forever. Of course, you're free to use those 5 slots as you see fit.
