Spectrorage replaces Navigator to mitigate energy drain. Arcane Energize should keep you topped up. Set up a dashwire, sit on it invisible, and fire away with [Artemis Bow Prime] (see Eternal Artemis Prime's Bow). Make sure to drop Spectrorage near you so that you can get energy orbs without having to come off of the dashwire. Make sure to hit headshots to proc Arcane [Rage].
