Koumei — Fate Weaver
Endgame build. Omikuji on cooldown. Stack Decrees all mission. Roar over Bunraku. The gun is the nuke; luck is the mods.

First Roll first
This loadout sits at Endgame. 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 RollWhy this build?
Endgame for Endurance, Duviri addicts, people who want twenty free mods by minute 20
Health: Not yet — Helminth, Steel Path, or Archon Hunts still closed. Play the Starter.
- Decrees stack with no cap worth caring about. Endurance Koumei is a snowball.
- Roar over 4 is the weapon-platform Helminth. Bunraku is the cost; threads still prime.
- Omikuji's Fortune is the augment that makes 2 a rhythm instead of a homework assignment.
Don’t use this for: ability-nuke as the damage · players without Helminth
Specialised investment for hard content
You don’t need the shards to run the loop. They are a later ceiling, not a gate.
Bring: A real Incarnon — Decrees can add elements, crit, fire rate, orbs. Build a flexible gun — Galvanized mods, crit, status. Boar Incarnon and friends complete challenges fast.
Alternative if…
- You don’t have Helminth yet → First Roll
- Star Chart only → First Roll
- New account or low investment → First Roll
- This is too much Forma / cost → Charmed Life — Optimised

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