Koumei vs Nova

Same Support / Healer fantasy — which support kit fits your squad and mission rota?

TL;DR — Quick Pick

Pick Koumei if…

  • You want the squad gap filled by Koumei's vibe — Test your luck with the dice-maiden.
  • This slot should feel like Kumihimo, Omikuji, and Bunraku, not a reskin of Nova's Null Star, Antimatter Drop, and Molecular Prime.
  • Your builds lean status effects and Koumei's passive extends that plan.

Pick Nova if…

  • You're sold on Nova's fantasy (Harness antimatter) more than another Support / Healer option.
  • Koumei's pitch (“Test your luck with the dice-maiden”) isn't what you're missing — Wormhole is.
  • You value Nova's orb-efficiency passive for longer ability spam on dense holds.
Verdict

Both fill the Support / Healer lane. Lean Koumei for status-duration amplification and Omamori; lean Nova for orb economy and Wormhole. Mission Usefulness is where they split: Steel Path (Strong vs Excellent — edge Nova).

When Each Shines

Koumei

  • Omamori carries mid-mission casts; Bunraku is the density payoff.
  • Status-heavy weapons in hand — Koumei's passive makes those procs earn their keep.
  • Missions that reward committing to Koumei's full ability loop instead of dabbling.

Nova

  • Wormhole carries mid-mission casts; Molecular Prime is the density payoff.
  • Long holds where energy comfort matters — Nova's loop stays online without babysitting orbs.
  • Nova shines on tile clears where ability damage — not just weapons — carries the pack.

Mod Scaling Focus

Koumei

Match the priority to your main ability — Strength or Duration first for most kits, then Efficiency, then Range.

STR
Raises damage and effect potency across Koumei’s Strength-scaling abilities.
DUR
Extends channeled / timed effects — often comfort on Koumei if the kit leans on buffs or zones.
RNG
Helps radius / targeting tools. Dump it if Koumei is mostly self-buff or exalted weapons.
EFF
Keeps ability uptime comfortable, especially on longer Steel Path missions.

Nova

Who Should You Pull?

Koumei
Pull Koumei if…
  • Status duration is how your weapons scale and Koumei extends that plan for free.
  • Your favorite clear starts on Kumihimo and ends on Bunraku — Koumei is built for that arc.
  • Nova's Wormhole loop asks for a different muscle memory than you want to practice.
  • Madurai on the aura slot matches the school you're already building weapons around.
  • Potato + Forma budget this month has Koumei's name on it.

Nova
Pull Nova if…
  • Energy / health orb rooms are common in your rota and Nova gets more mileage out of every pickup.
  • Squad comps where someone has to own tile clear alone — Nova is the frame you trust for that job.
  • Koumei can stay on the shelf; Nova is the one you'll actually Forma twice.
  • Nova rates higher on Steel Path holds (Excellent vs Strong) — that rota is where you actually play.
  • Your endgame loadout screen should show Nova before it shows another same-role experiment.
