Harrow vs Koumei

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

TL;DR — Quick Pick

Pick Harrow if…

  • You want the squad gap filled by Harrow's vibe — Achieve redemption through vengeance.
  • This slot should feel like Condemn, Penance, and Covenant, not a reskin of Koumei's Kumihimo, Omikuji, and Bunraku.
  • You're buying into Harrow's passive — overshield capacity doubled.

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 Harrow's Condemn, Penance, and Covenant.
  • Your builds lean status effects and Koumei's passive extends that plan.
Verdict

Both fill the Support / Healer lane. Lean Harrow for Thurible and Thurible; lean Koumei for status-duration amplification and Omamori. Mission Usefulness is where they split: speed clears (Excellent vs Situational — edge Harrow).

When Each Shines

Harrow

  • Mod focus stays on match the priority to your main ability so the cast loop doesn't fall over mid-rota.
  • Missions that reward committing to Harrow's full ability loop instead of dabbling.

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.

Mod Scaling Focus

Harrow

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

Who Should You Pull?

Harrow
Pull Harrow if…
  • Thurible into Covenant is the cast story you want to master — not a random subsume mashup.
  • You'd rather specialize hard into Thurible than stay generic in the Support lane.
  • Skipping Koumei frees a craft slot — you'd rather finish Harrow properly.
  • Harrow rates higher on speed clears (Excellent vs Situational) — that rota is where you actually play.
  • Inventory space / foundry queue: Harrow jumps the line over another Koumei craft.

Koumei
Pull Koumei if…

  • Your favorite clear starts on Kumihimo and ends on Bunraku — Koumei is built for that arc.
  • Harrow's Thurible 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.
