Koumei vs Oberon

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.
  • Oberon's pitch (“Healing and suffering do Oberon’s bidding”) isn't what you're missing — Omamori is.
  • Your builds lean status effects and Koumei's passive extends that plan.

Pick Oberon if…

  • You're sold on Oberon's fantasy (Healing and suffering do Oberon’s bidding) more than another Support / Healer option.
  • Koumei's pitch (“Test your luck with the dice-maiden”) isn't what you're missing — Renewal is.
  • You value Oberon'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 Oberon for orb economy and Renewal. Mission Usefulness is where they split: Steel Path (Strong vs Excellent — edge Oberon).

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.

Oberon

  • Renewal carries mid-mission casts; Reckoning is the density payoff.
  • Long holds where energy comfort matters — Oberon's loop stays online without babysitting orbs.
  • Dense spawns where Oberon's cast cadence outpaces gun-only clears.

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.
