Caliban vs Koumei
Same Support / Healer fantasy — which support kit fits your squad and mission rota?
TL;DR — Quick Pick
Pick Caliban if…
- You're sold on Caliban's fantasy (The heir of twin kingdoms ascends) more than another Support / Healer option.
- You'd rather build around Lethal Progeny than live in Koumei's Omamori loop.
- You're buying into Caliban's passive — allies within Affinity range gain up to a percentage resistance to the types of damage they are….
Pick Koumei if…
- You want the squad gap filled by Koumei's vibe — Test your luck with the dice-maiden.
- Caliban's pitch (“The heir of twin kingdoms ascends”) isn't what you're missing — Omamori is.
- Your builds lean status effects and Koumei's passive extends that plan.
Verdict
Both fill the Support / Healer lane. Lean Caliban for Lethal Progeny and Lethal Progeny; lean Koumei for status-duration amplification and Omamori. Mission Usefulness is a wash — decide on kit feel and passive, not the rating table.

When Each Shines
Caliban
- Lethal Progeny carries mid-mission casts; Fusion Strike 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.
- Missions that reward committing to Caliban'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
Caliban
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 Caliban’s Strength-scaling abilities.
- DUR
- Extends channeled / timed effects — often comfort on Caliban if the kit leans on buffs or zones.
- RNG
- Helps radius / targeting tools. Dump it if Caliban is mostly self-buff or exalted weapons.
- EFF
- Keeps ability uptime comfortable, especially on longer Steel Path missions.

Who Should You Pull?
- Lethal Progeny into Fusion Strike is the cast story you want to master — not a random subsume mashup.
- Squad comps where someone has to own tile clear alone — Caliban is the frame you trust for that job.
- Koumei can stay on the shelf; Caliban is the one you'll actually Forma twice.
- Even after Helminth, Sentient Wrath and later abilities are still the reason Caliban earned potato.
- Your endgame loadout screen should show Caliban before it shows another same-role experiment.
- 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.
- Caliban's Lethal Progeny 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.
