The build doesn't require a lot of energy. I started working on this using my regular armor which has only a single Attunement rune and a Radiant headwrap for a total of 33 while holding an urn. It worked, so I didn't bother tweaking it. Use anything, really anything, for a weaponset. You won't see it in play much because you'll always be holding either Khanhei's or Xiko's dusty remains.
Here's how it works:
Cast Resilient Weapon and wait for your energy to max out, then aggro a group. Cast VwK just before they engage you. From now on, we'll generally be activating our skill from right to left. If we catch the right rhythm, that's all we need to do to kill this group.
After a second or so of being pounded by vermin, activate Balanced Stance. We do this well in advance of the skills we want it to protect from knockdown, so it can start recharging for a possible 2nd use.
When VwK starts flashing, activate Weapon of Shadow and Resilient was Xiko in quick succession. Degeneration won't be more than 1 pip, and blind vermin don't put on much pressure. Now we wait for VwK to recharge. Throw in a Wielder's Boon whenever our health drops a bit.
When VwK is almost ready, activate Dolyak Signet, to protect our next few spells from knockdown. Activate Bonetti's Defense, if you can, after a final Wielder's Boon puts us at full health. It's practically always fully charged at this point from the hits we've been taking. VwK being ready, we can always abort our Bonetti's, but waiting a bit serves two purposes: We're buying time for our other skills to recharge, and when we'll be starting our second cycle at full energy. If some hits start landing and we're getting nervous, screw Bonetti and just hit VwK. Also, if Bonetti somehow didn't charge, activate VwK as soon as the vermin can see again and start hitting us.
When we recast VwK, Xiko will clean up bleeding and poison, but the vermin will have those back on us soon enough, so cast Resilient Weapon to complete the cycle. If there's still living vermin around when VwK starts flashing again, repeat the cycle, starting with Balanced Stance. It should be recharged by now if we activated it at the right time.
This is a very easy build to use, just a keygrinder. Right to left, repeat. If you do it right it works without fail. Word of honor.
And now for the one drawback: It can't deal with Shreader, so stay away from him.

Did I mention there's always 1 and often even 2 chests involved? Bring lockpicks and be sure to scoop up the Celestial loot.

EDIT: Added the template code. Can't believe I forgot that.
