Omamori

Surround yourself with Omamori Charms, each with a chance to have enemy attacks heal you instead of damage you. The number of charms is determined by Koumei's dice roll. A roll of triple sixes grants invulnerability for the duration of your Omamori Charms.

Info

  • Omamori is Koumei’s ability 3.
  • Surround yourself with Omamori Charms, each with a chance to have enemy attacks heal you instead of damage you.
  • Use it with the rest of the kit — especially Kumihimo, Omikuji — instead of casting it in isolation.
  • Ability Strength, Duration, Range, and Efficiency each matter differently; check Mod Scaling below before dumping all four.

Tips & Tricks

  • Read the battlefield first — cast Omamori when it actually solves the room, not on cooldown habit.
  • Pair Omamori with movement and energy economy so you’re not stranded after a big spend.
  • On Steel Path, confirm whether Omamori still carries without strip, Viral, or a squad buff.
  • If you never press 3, it’s the first Helminth candidate on Koumei.

Mod Scaling

Strength

Improves Omamori’s damage or effect potency where Strength is listed on the ability.

Duration

Extends how long Omamori’s effect lasts.

Range

Range is usually dumpable on Omamori unless you feel the hitbox is too tight.

Efficiency

Omamori costs energy each cast — Efficiency (or strong regen) keeps the loop comfortable on long missions.

Priority

Stack the stats that actually move this ability’s needle, then Efficiency for uptime.

Mission Use Cases

MissionHow to Use It
Steel Path Survival / Defense / DisruptionTest whether Omamori still clears or enables clear when enemies are dense and overlevelled.
Mobile Defense / ExcavationUse Omamori to control or delete the swarm on the objective, then reposition.
Exterminate / Capture Speed RunsCast Omamori only when it saves time — skip it on empty tiles.
Spy / Rescue / Quiet RoutesIf Omamori is loud or forces combat, save it for after the vault; if it’s stealth-friendly, use it to stay safe.

Comparisons

  • VS

    Vs similar tools on other frames — Omamori is tuned for Koumei’s loop — don’t judge it as a standalone subsume without the rest of the kit.
