Energy-free, solo Steel Path survival build. [Path Of Statues] keeps [Atlas]' rubble up without the need for Petrify. Keep punching as fast as you can (amber shards help) to keep [Atlas] invincible as much as possible.
For Dark Sector nodes, swap Molt Augmented for Arcane Energize. You don't need the extra damage against infested, but in case you drop below 1400 rubble, you DO need a way to quickly [Recover] your energy from Ancient [Disruptor] attacks.
Can be run with Naramon but is not absolutely necessary. For solo Steel Path survival, you'll probably be punching enemies so often that the combo duration boost from secondary dexterity will more than suffice. I just start the mission with an energy pizza so I can Petrify enough enemies to get the meter above 1400. Then I punch about 4,000 times and call it a day.
