Recently, I have seen comments from people that don't think recharging a Nova Bomb completely with a Nova Bomb was possible. Although this isn't my smoothest run (and typically stealth Hunter is an easier way to get through it), this remains my favorite Warlock activity. Build - Obsidian Mind, bloom, annihilate and scatter grenades. Melee restores health just in case. And of course, max agility, +2 agility MIDA, and Blink for good measure... because fast is fun.
