While Atlas has always been a solid tank whose punches deal impressive damage to mid- to high-level enemies, his chief weakness has long been the ability's poor scaling against highly-armored endgame opponents.

The Helminth system has provided [Atlas] with an excellent solution to this issue in the form of [Hildryn]'s Pillage. This ability allows [Atlas] to strip more than half of surrounding enemies' armor instantly, and can stack with itself to whittle it down to nothing. While [Atlas] is usually considered an HP tank, the shield restoration aspect of this ability is appreciated too, as it allows [Atlas] to more easily gain [Adaptation] stacks and gives him some brief invulnerability when it resets his shield gate.

This build is excellent for Isolation Vaults, since after stripping its armor several times, [Atlas] can destroy a Necramech in just a couple punches with no fear due to his 1's invincibility. In addition, [Ore Gaze] lets you maximize your drops along the way.

As for this build itself, you'll notice this doesn't look any different from a traditional [Atlas] build, and this is part of why Pillage fits so nicely in his kit. High strength makes for faster armor strip, and the full Umbral set makes him exceptionally tanky. You could even Umbra Forma him in order to add [Power Drift] and potentially a different aura. The augment slot is flexible: [Ore Gaze] is very nice for Isovaults and short farming runs, while [Rubble Heap] is excellent for long endurance runs.
