Foreword
This was made a new player in mind who might not have that much gold, transmutes and tel vars at their disposal. Race can be anything, adjust jewellery glyphs as needed.
Gear options
I chose Robes of the Hist because it has defensive and offensive stats and you can either farm it easily in Shadowfen, or buy it from Guild Traders for fairly cheap I would presume. Even better option is probably Rallying Cry which is probably fairly cheap these days as well. One setup is with Robes of the Hist, one with Rallying Cry. Stuhn's Favor is great because it's craftable so easy to get and you can control what weight you want it in.
If you need more sustain you could try e.g. Engine Guardian instead of Balorgh (or Roksa but that's harder monster set to get). If you feel like blocking more switch one or both of the Impenetrable pieces to Sturdy. If you want to roll dodge more then switch them to Well-Fitted instead.
If you have Vateshran Frost Staff run that instead on the backbar in the Robes of the Hist setup. If you feel like you need more healing then try switching the Living Dark skill into Resolving Vigor.
Make the weapons golden, armour purple and jewellery can be blue at start.
Fight
The rotation is roughly this: Channeled Focus, Elemental Susceptibility, Elemental Blockade, Toppling Charge, Dark Flare, Dawnbreaker Ultimate, Sweep Sweep Sweep and then execute with Jesusbeam. Use Extended Ritual when you need to purge and go back to backbar to heal yourself when needed.
The idea is that you proc Off Balance with Toppling Charge, and then do damage on your frontbar with Stuhn active so you increase your penetration.
Other
Try the different foods, see what feels good for resource sustain. You could also use Sustained by Suffering instead of Juggernaut.
