Loadout and gear
Set Arc Conduit or Plasma Circuit with Arc Lattice, Circuit Spike, Firewall, and System Crash. Plasma Circuit has 7.6 m base primary reach and Arc Conduit has 6.75 m. Four Furnace Link pieces improve skill damage and cooldowns. Two Echo Relay pieces add skill damage.
Null Pulse changes Firewall into twin laser sweepers. Keep ordinary Firewall if the slowing zone matches how you use doorways. Choose a safe firing lane before placing either version.
Pack and guardian rotation
Use Arc Lattice on grouped enemies, then put Firewall at the lane they must cross. Fire primary from outside contact range. Circuit Spike is a narrow single-target breaker up to 8.2 m, useful when a dangerous enemy remains behind the first wave.
When a pack collapses around you, System Crash applies area silence and can interrupt. Reposition on a clear floor before your next Arc Lattice. Against the guardian, keep the sight line clear instead of backing around a corner just as a telegraph ends.
Leveling priorities
All four starter skills are available at level 1. Put early upgrades into slots you wear regularly and use rank milestones at levels 7, 13, 19 and 25 to cycle charged skills more often. Run at least one reserved Circuit Spike charge into a guardian room. Firewall and Arc Lattice can take the first pack without spending the breaker.
Extraction and recovery
Check backpack room early, then choose the correct descent or extraction gate after the guardian dies. If you are cornered, use your dodge or a slowing Firewall to make space before attempting the next cast.
