Koumei vs Sevagoth

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.
  • Sevagoth's pitch (“No longer adrift in the Void, Sevagoth has returned”) isn't what you're missing — Omamori is.
  • Your builds lean status effects and Koumei's passive extends that plan.

Pick Sevagoth if…

  • You want the squad gap filled by Sevagoth's vibe — No longer adrift in the Void, Sevagoth has returned.
  • This slot should feel like Reap, Sow, and Exalted Shadow, not a reskin of Koumei's Kumihimo, Omikuji, and Bunraku.
  • You're buying into Sevagoth's passive — on death, become Sevagoth's Shadow and fight to resurrect him by collecting the souls needed to….
Verdict

Both fill the Support / Healer lane. Lean Koumei for status-duration amplification and Omamori; lean Sevagoth for Gloom and Gloom. Mission Usefulness is a wash — decide on kit feel and passive, not the rating table.

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.

Sevagoth

  • Gloom carries mid-mission casts; Exalted Shadow is the density payoff.
  • Mod focus stays on match the priority to your main ability so the cast loop doesn't fall over mid-rota.
  • Sevagoth 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.

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.
  • Sevagoth's Gloom 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.

Sevagoth
Pull Sevagoth if…
  • Gloom into Exalted Shadow is the cast story you want to master — not a random subsume mashup.
  • Squad comps where someone has to own tile clear alone — Sevagoth is the frame you trust for that job.
  • Koumei can stay on the shelf; Sevagoth is the one you'll actually Forma twice.
  • Even after Helminth, Sow and later abilities are still the reason Sevagoth earned potato.
  • Your endgame loadout screen should show Sevagoth before it shows another same-role experiment.
