Atlas
Petrify Weapon Platform
Gun-leaning Atlas — Petrify locks the room, a Helminth buffs weapons, and Landslide is mobility / panic i-frames instead of the clear plan.

Guns carry while Petrify softens packs.
Petrify to lock packs, shoot under a Helminth damage buff, and treat Landslide as mobility / panic i-frames instead of the main DPS plan.
Atlas cannot be knocked down while grounded. Rubble from petrified kills and Rumblers is his second resource — armor, healing, and (with Rubble Heap) free Landslide casts once you hold a high pile.
Strength for the weapon buff and Petrify vulnerability; Duration for gaze uptime.
Helpful for Petrify cones when you are not punching every pack.
Roar is the generalist gun buff. Eclipse rewards standing still on objectives. Nourish covers Viral + energy.
Petrify locks packs while Helminth-amped guns clear — solid when you are tired of punch strings.
Petrify locks the objective while guns delete.
Gun clear with stone CC — faster than banking rubble for Fist Economy.
Still a loud melee-adjacent kit; not a Spy specialist.
Camp stages reward Petrify + guns; travel stretches lean on Operator / Archwing.
Better than pure fists if your guns already reach; still not an Eidolon frame.
