Hello there.

In this guide you will learn how to become a literal god. If you read the entire guide, any mission will become a breeze. You will be immune to mosquitos and they will straight up die when trying to [Bite] you. You will learn how to transcend space and time. You will [Reach] the perfect state of being. Will you turn into one of the pillar men? Will you become orange man? Or will you turn into the living embodyment of [Revenant]? Choose any state of perfect being you desire to be.

In this guide, I will not only explain his kit but also give instructions on the two different general playstyles you can use on [Revenant].

This build is solely focussed on Reave, Mesmerskin and (mainly) Danse Macabre. The 1st ability is not to be used here. You can replace it with a different ability using Helminth if you want to. I recommend Subsuming Whisp's 3rd ability, empower or maybe dispensary.

If you want to specialize to go into different content, look at my other builds. All of my builds fit onto the same Warframe.

Hybrid build: https://overframe.gg/build/119385/

Reave build: https://overframe.gg/build/119386/

Illegal build: https://overframe.gg/build/195657/

Lets go.

[Revenant] is a great Warframe for both endurance runs and normal missions. His kit does a lot of things. Some absolutely broken, some mediocre and some totally useless.
Some mechanics, which would be totally broken on other frames, get rendered useless because of how OP his kit is. As a Revenant, you go to infinity and beyond. Literally.

Info dump warning

Revenants kit:

His 1, Enthrall, is a CC that converts 1 enemy to a slave. Maximum of 7. If a slave shoots an enemy, that enemy turns into a Slave. If a slave dies, it spawns a bonfire that shoots out homing missiles that do decent damage and enslave more dudes. Huge snowball potential.
Some "deeper" mechanics for those who give a shit: Host thralls (i.e. the ones you personally create) share their duration with the thralls they infect. Recasting Enthrall does not refresh the ability duration on existing thralls. Thralls created by the bonfires count as host thralls, but they don't leave behind another bonfire.

His 2, Mesmerskin, is a 100% damage reduction. This doesn't have a duration, it has layers. 6 layers base (and 14/15 with this build) to be exact. Each time you get shot, you loose 1 layer. Once a shot hits, that enemy can only take away another layer after 5 seconds. This is not affected by mods. The enemy will be stunned for 5 seconds (base) and 10 seconds with this build. Status procs will not affect you while you have this ability active. But they will put you to 2 hp, which is not a problem as you can't die from them. This includes magnetic procs.

His 3, Reave, is a very fast and steerable dash during which you become invincible. Upon hitting an enemy, that enemy always looses 8% of their health and shield (base) or 20% with 250% strength, which is the important part. A thrall however will always lose 40% of their health and shields (base) or 100% if you have 250% strength., which we don't have in this build. That means you'd onehit any thrall if you have 250% strength. It'd deal infinite damage. The lost health and shields will heal you/replenish your shield. This mechanic can be overlooked as you don't take damage anyways. Every Thrall you hit with Reave will replenish your Mesmerskin by 1.

His 4, Danse Macabre, is a strong aoe that fires horizontal beams in a 100m radius. This is not affected by range. They have a 20%/40% proc chance and it deals 20400/40800 base dps (or around 52.000/104.000 dps with this build) depending on wether you hold down left click/melee or not. It will always proc the "perfect" status and deals the "perfect" damage type. Corrosive (aromor), Magnetic (shields), Poison (red health). It has some damage falloff. So it will be effective until you are about 30 meters away. The beams can penetrate thin walls. Danse Macabre costs 5/10 energy/s with this build (base 20/40), again, depending on wether you hold down left click or not. This is also the lowest you can go. In energy consumption, not your life, you have probably gone really low in that one.
Due to the relatively small effective range, you can and should cast Reave often. It activates instantly and costs only half the energy cost during Danse Macabre.
Due to the high drain, I always use Arcane Energize which will enable me to stay in my ultimate for many minutes at one time and the downtime (if any) is at most 15 seconds. Each slave you kill with Danse Macabre will drop 50 overshields.

Playstyles:

There are two general playstyles you can use that are most effective. You can obviously also use a melee slash build or some other thing that's meta but that has nothing to do with this build.

In normal missions, you keep Danse Macabre active all the time. It has a relatively small effective range but deals huge ammounts of damage. Always be sure to cast Danse Macabre while going fast, it somehow affects how fast you move. Sprint speed mods also affect how fast you go in Danse Macabre. And if you are still having problems, the third ability is your friend.
Reave can be cast instantly and for only half the cost during Danse Macabre. Reave is steerable and it can be canceled at any time. So you can use it to jump right into the face of the enemy to roast them. This is not good for any mission that does involve stationary gameplay. i.e Defense. But it is good for anything else due to the obvious mobility advantage. Mesmerskin should be kept active at all times. You can just recast it whenever it is low. Shield gating helps with that. You literally can not die if you recate your Mesmerskin before it is fully depleted as shield gating gives you 1.3 seconds of invulnerability.

There is also the Reave centered playstyle. Which we can not use in this build. Its only really efficient on long survivals. But it is quite fun and satisfying, in my opinion. You cast Enthrall and Reave your thralls frequently. Using the mechanics of this combo, you have permanent 100% damage reduction from Mesmerskin, which will be replenished with each kill, and you onehit anything around you. It is more than enough to sustain life support in a survival mission.

So why do i recommend this build?
This build is great for easy and efficient gameplay on [Revenant]. It keeps you engaged with the "high" energy drain but as you are moving around and thus collecting enough energy anyways, it's just great. With a little bit of training in using Reave, this build is just a crap ton of fun and really efficient.

Feel free to contact me if you have any questions or things that i can add to all of this information and also leave a comment because I like reading those :3 Discord server: https://discord.gg/F5Mk9mr7uD

And that's it! hope this helped. Check out my other builds too if you want to specialize into other playstyles or if you want to play his entire kit at once! Cheers! Leave a rating if u want to, I'd appreciate it ;)
