This is my personal General Use [Atlas Prime] build.
Works in literally every type of mission always get top damage, is super comfy to use, and is tanky as hell.

How does this build work?
Keep up the Wrathful Advance buff going, and just slap enemies with your 1. Occasionally when you see a big group cast Petrifying Gaze to get some rubble stacks. You should not lack any tankiness, as you get shield gating from Augur Secrets and you are invulnerable while casting 1. Level cap is easy to survive with this setup. If you have [Grimoire], just cast it's alt attack once in a while into a group of enemies.

Why those mods?

Aura: [Atlas] is flexible with auras. If you have a pet that can provide armor strip for you, I'd personally take Growing Power, otherwise either Corrosive Projection or Steel Charge Would be my picks.

Exilus: [Power Drift] is here for some nice bonus 15% strength, and the knockdown immunity chance is nice if you screw something up while in the air.

[Umbral Intensify] is used to grant us a 77% increase in Strength, giving us a huge damage bonus.
[Umbral Vitality] is here to make us way more survivable, giving us A LOT of health, which is affected by our ~3k armor, granting us over 90% damage reduction, while also lifestealing using our Rubble passive, although a healing pet, or other source of healing would be recommended so we can actually stack rubble up.
[Umbral Fiber] is used simply to enhance other Umbral mods, and give some overkill armor, it can be swapped out for something else to make the build not require an umbra forma anymore.
[Path Of Statues] is core of this build. Grants us insane CC and a way to get rubble.
[Rubble Heap] is a nice damage bonus in long endurance missions, you can swap it for other augments like [Ore Gaze], if you would like some sweet bonus loot.

Why those arcanes?
Molt Augmented is simply a nice damage bonus, nothing else, isn't necessary, can be replaced with energize or whatever you prefer if you want to, Augmented is just my preference.

Arcane [Fury] boosts melee damage significantly, another nice damage bonus, but not required.

Helminth?

[Atlas]' 2 is literally useless in my opinion. I prefer slapping damage buffs in there, Wrathful Advance is required if you want to hit that sweet sweet damage cap.

Shards?

5x Tauforged red for more strength, as his 1 scales exponentially with str (damage of his 1 gets multiplied by str, then esentially gets multiplied by it AGAIN due to Wrathful Advance)

What else should I use?

Remember to slap Melee Exposure on your melee! Any rank is okay, as you will be stacking it up so fast you will barely notice any difference between the ranks.

Either Zenurik or Grimoire with Xata Invocation to get enough energy orbs to spam abilities, you can also use energize and/or Equilibrium (I would recommend swapping it in for Augur Secrets, although that would require a second umbra forma. You may also get rid of Umbral Fiber for more strength, although the tankiness and bonus 22 strength you get for it is a good deal in my opinion.

As for pets: I personally use a Panzer with healing, to grant me Viral for more of the sweet damage, but any pet you choose is good.

I HEAVILY recommend a good stat stick, although stat sticks will soon become deprecated. Although the stat-stick build will just be slapped on the exalted instead.
