Frost — Impedance Hall

Steel Path build. Ice Wave Impedance paints a slow trail. Hallways become ice rinks. Avalanche is backup, not the spam button.

Wrong drop or mechanic?

Why this build?

Steel Path for Defense corridors, Interception, people who like floor CC more than strip math

Health: Not yet — Helminth, Steel Path, or Archon Hunts still closed. Play the Starter.

Play this in Level capPlay this in Defense
  • Impedance is the augment that makes 2 a deployable, not a cone of chip damage.
  • This is slower than Avalanche strip in a packed Exterminate and better on a chokepoint.
  • Duration mods are the damage here — a dead trail is a dead build.

Don’t use this for: open tilesets · Exterminate speedruns

Stronger mods, Arcanes, real synergy

You don’t need the shards to run the loop. They are a later ceiling, not a gate.

Bring: Any weapon — You are slowing, not nuking. A status primary finishes what the ice holds.

Did this still work for you?

Your note, in this browser. Separate from Codex verification — the stamp on the card is editorial, this is yours.

Readiness

  • Required mods 0/9 · required — 0/9 named
  • Forma 0/3 · required — 3 on the card. Codex does not track installed Forma.
  • Helminth · optional — Not required
  • Arcanes · recommended — 0/2 recommended
  • Shards · optional — Optional unless the card says a breakpoint

Investment: 3 Forma · Reactor · 2 shards · 2 specialised mods. Typical farm ~1–2 hours. Trade if a route is vaulted.

Codex Checked · Compared against current game data for this update. · Update 43.5 · 5 Sept 2026 · PC · Current

Medium confidence. A solid recommendation with more situational dependencies. Confidence is not verification. Verification is separate: Codex Checked against Update 43.5.

Your next step

Next: Whiteout — Optimised

Unlock Helminth, Steel Path, or Archon Hunts before this upgrade is honest.

Tonight

What is actually up

30 minutes, one hour, or two — matched to this loadout, not a dump of the Origin System.

  1. 30 minutes

    Farm Corrosive Projection

    One named gap. Open Nightwave

  2. 60 minutes

    Corrosive Projection, then Forma

    Finish the missing named card, then spend a Forma if a polarity is still fighting you.

  3. 120 minutes

    One Archon Hunt

    If you are logging off after this, stop at the named component. Do not start a second Forma session tired.

Rink loop

Pocket card. Stick this on a second screen; the long version is the mission below.

  1. 1Ice Wave (2) down the lane they have to walk. Impedance ice sits there and crawls them.
  2. 2Snow Globe (3) on the objective behind the rink.
  3. 3Avalanche (4) if a dense wave ignores the floor.
  4. 4Do not Ice Wave at your feet in an open tile. It is a corridor tool.

First mission — press these buttons

  1. 1

    Paint the door

    2

    2 down the lane. A sheet of ice sits there.

    You will know it worked when: A lingering ice path. Enemies crawl.

  2. 2

    Globe behind it

    3

    3 on the pod. You now have a rink and a house.

Common mistakes

  • Ice Wave in an open tile

    No floor path, no value. Go play Avalanche.
