Loadout and gear
Use Phantom Edge with Shadowstep, Fan of Blades, Phase Guard, and Phantom Execution. Four Veil Circuit pieces add critical chance and speed, and two Harbor Vanguard pieces add defense. Ambush Protocol is a Season 0 firmware option for a build centered on first contact. Shadowstep opens an Ambush window in WAR.
Pressure and peel
Approach from a different angle than your ranged teammate. Shadowstep through the exposed edge of the fight, use Fan of Blades to slow opponents who try to leave, and reserve Phase Guard for counterpressure. Phantom Execution offers brief control and applies a mark.
Use a second Shadowstep to reset behind cover before your escape route closes. Against a Warden, wait for the barrier to expire or go after a less protected angle. On the Monorail, secure a stable landing before committing to a dash.
Objective timing
On a relay, use the threat of a flank to force an opponent to turn while your ally contests. In Grudge Pit, an early dash into active control is an easy punish. Test the range first with Phantom Edge, then use the remaining charges to exit or confirm the next opening.
