Loadout and formation
Use the native Control Rod and rotate Needle, Screen and Sweep by availability. Four Heliograph pieces give attack and defense, and two Cryo Warden pieces give 8% Integrity. Use Embedded gear for its slot stats. WAR firmware bonuses should not be carried over into the native dungeon rotation.
Choose a grounded Needle angle away from the party’s step-out lane. Keep Screen unspent before a forced crossing, and Recall drones from a finished hallway before the next mechanic. The native Screen is local to the Shepherd, so tell the party where you are holding rather than calling it a squad barrier.
Conduit Vault
Take a pylon job or cover the approach while another runner connects it. Move into the current safe ring and leave a clear path for a class with a verified breaker. Assign Core Overload to a teammate with Circuit Spike, Shield Bash, Phantom Execution or Counter-Pulse. Needle and Sweep are damage options for the four-second window after the three-second channel is broken.
Avoid committing a Sweep through geometry or beginning a long cast sequence when a ring is about to land. If Unified Array is charged, start it when the group’s breaker succeeds and your surviving drones will be able to contribute.
Cryo Foundry
Cross from vent to vent as a group and keep at least one runner free to interact at the far valve. During ice prison, stop trying to damage the Titan and fracture the prison three times. After the release, use Needle and Sweep from safe ground while the exposed Titan is available. Save Screen for the next move between positions.
