One of the best frames in the game gets a build where I am not even sure how to kill myself. Running this build in all gamemodes is so simple, yet so effective.

Abilities: All your abilities play a role here. Make sure Mesmer skin is always active. This will shield you from incoming damage and stun anyone who hits you. make sure to pay attention to who hits you because you can cast Enthrall on them with no energy cost. Speaking of Enthrall, you're going to want to cast it quite a bit. Cast it and let your thrall army grow(It will automatically when your thralls attack other enemies). This is why duration is necessary, so your thrall army lasts as long as possible. However, periodically you should use Reave on a group of your thralls. If Molt Augmented has stacked enough, you should be able to one shot every thrall you hit with reave. This is how you kill enemies. Thrall them, let your army grow, and Reave them. It should also be noted that killing thralled enemies with Reave recharges your mesmer skin without having to recast Mesmer skin. So if you play your abilities right, you should never take damage, ever. Lastly, use Danse Macabre when surrounded by a group of non-thralled enemies. Enthrall does have a capacity limit, so use Danse Macabre when that limit is reached, and a group of enemies is near you. Your increased ability strength should provide enough damage to kill them.

Weapons:
You are mostly free to use whatever weapons. It shouldn't matter because your abilities are so dominant. However, I do recommend the [Phantasma], as it is a strong status weapon made for [Revenant].

Archon Shards:
Use Crimson Archon shards, and focus on ability strength, duration. However, I do advise using 1 or two Amber shards to increase energy orb effectiveness. This will help your energy economy greatly because we will be using a lot of energy, and want to make the most out of the energy orbs we pick up.

End result:
A truly dominant warframe that runs circles around the battlefield. I use [Revenant] when i want to solo bounties on Orb Vallis or Deimos. He is the definition of a powerful, self sufficient, and functionally invincible warframe.
