KoumeiMarionette Room

Optimised build. Bunraku as a status marionette. Range, Strength, a cone of doomed dolls. Omamori still stays up.

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

Dense tiles, grouping, people who want Koumei to press 4

Wrong drop or mechanic?

Don’t build this yet

First Roll first

This loadout sits at Optimised. It wants Forma, Helminth, or shards you may not have. Play the Starter until those systems are open — then this page is the upgrade, not the homework.

Open First Roll

Why this build?

Optimised for Dense tiles, grouping, people who want Koumei to press 4

Health: Not yetHelminth, Steel Path, or Archon Hunts still closed. Play the Starter.

Play this in Steel Path
  • Bunraku is the CC and the primer. It is not a level-cap nuke on its own.
  • Arcane Impetus loves unique statuses. Koumei prints unique statuses.
  • Keep Omamori. A marionette mage with no charms is a 122-shield frame.

Don’t use this for: ability-nuke as the damage

Helminth, shards, and a finished configuration

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

Bring: Condition Overload melee / Galvanized gunsBunraku dumps statuses. Your weapons should read that. Galvanized Aptitude, Galvanized Shot, Condition Overload.

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: Charmed Life — Endgame

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 Growing Power

    One named gap. The Silver Grove quest

  2. 60 minutes

    Growing Power, 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.

Who this is for

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

  1. 1Omamori (3). Always first.
  2. 2Kumihimo (1) the lane so they walk in primed.
  3. 3Bunraku (4) the clump in front of you. Triple sixes wraps behind too.
  4. 4Shoot the dolls. Status weapons go stupid here.

First mission — press these buttons

  1. 1

    Face the pack, press 4

    4

    Long animation. They should sag on strings.

    You will know it worked when: Marionettes. Status icons stacking.

  2. 2

    Shoot

    Do not recast 4 on one leftover. Recast on the next clump.

Common mistakes

  • Casting 4 with your back to the room

    It is a front cone unless you triple-sixed.

When this feels easy

  1. 1Casting speedThe animation is the cooldown that matters.
