Power Conduit
A Spear and Greatsword power Conduit for the zerg — Berserker's and Marauder under 
Scholar runes.
The legends are 
Legendary Assassin Stance and 
Legendary Entity Stance, so your whole utility bar is Shiro and Razah: 
Impossible Odds and 
Phase Traversal to get on a target, 
Jade Winds to stun it, 
Gladiator's Defense to break out when it goes wrong. The Conduit line itself deals no damage — it pays you back energy, endurance and health for the energy you spend.
Why these traits
Conductive Armaments grants affinity whenever you use a weapon skill that costs energy, and 
Expanded Consciousness turns that affinity into healing and endurance, then into energy once you cap it. Neither one is a damage modifier: the damage is Devastation and Invocation. 
Unsuspecting Strikes hits foes who are still healthy, 
Brutality hits foes carrying 
Stability or 
Protection — which in a zerg is most of them — and also hands you 
Quickness on weapon swap, while 
Notoriety makes each stack of 
Might worth more power and gives you might for using a legend skill. 
Rising Tide and 
Roiling Mists finish it, and 
Enhanced Embodiment shortens legend invokes, which matters because Notoriety, 
Spirit Boon and the minor 
Invoker's Rage all pay out on the invoke.
Gear reasoning
Berserker's and Marauder: power, precision and ferocity, with the Marauder pieces adding the only defensive stat on the character. Scholar is six lines of power and ferocity and nothing else — no health threshold, no defensive bonus. 
Bloodlust and 
Force are flat damage, 
Fire rides your crit chance, 
Hydromancy chills on the weapon swap you are already making for Brutality's quickness, and 
Thief pays strike damage for hitting with weapon skills that cost a resource — which, on Revenant, is what you are doing anyway. The real defence is the consumables: 
Mists-Infused Spherified Peppercorn-Spiced Oyster Soup for the incoming-damage reduction, 
Writ of Masterful Strength for power while you are still above the threshold.
When not to run it
The affinity loop starts with weapon skills that cost energy, so this build has to be in range and spending. Playing it at max range on the Spear starves Conductive Armaments, and with it Expanded Consciousness — you end up a Devastation Revenant with an idle elite line.
It also gives the squad almost nothing. Spirit Boon passes boons to nearby allies when you invoke, and that is the whole of it: no ally healing, no ally cleanse, no ally Stability. If the squad needs a body that supports rather than another one on the damage pile, take the Heal Vindicator.
