This is the extreme low budget Nyx Interception build with ZERO potato and/or forma. I mostly use this build for Steel Path Incursions and I never had to scramble between capturing and defending the points.

[Nyx] is very convenient for Interception as you do not need to put much thought or effort in the gamemode. All you have to do is press Chaos for the map wide CC and initial stun. If any enemy still attempts to capture a point, pressing Chaos instantly stuns and stops them. Sit at the center of the map and spam 3 for best results.

Any aura is fine as long as it has dash.
You can forgo efficiency for more duration.
May require Zenurik focus for Energizing Dash.
