Loadout and gear
Run Phantom Edge with Shadowstep, Fan of Blades, Phase Guard, and Phantom Execution. Four Veil Circuit pieces support movement between jobs. Two Cryo Warden pieces give more room for mistakes on the approach. Shatter Core supplies a delayed decoy, so use Phantom Execution for your planned instant Vault interrupt.
Conduit Vault assignments
Use one Shadowstep charge through the active laser or coolant and save a charge for the plasma corridor. As the mobile runner, take Pylon B while your teammate remains tethered at A. Stay together near the chamber before you advance.
Aim Phantom Execution at the Overseer within its 5.1 m cone as soon as Core Overload begins. Follow the successful break with primary hits or Fan of Blades. Save Shadowstep for the next safe ring or a clean exit when the warning appears.
Cryo Foundry assignments
Use Shadowstep between thermal vents during the freeze cycle. Move to the far coolant valve if your teammate already covers the near one. At the Titan, hold a Shadowstep charge for reaching the frozen runner and interact three times before returning to damage. If you are frozen, use the same interaction from inside the prison.
