Caliban vs Kullervo

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.
  • This slot should feel like Razor Gyre, Sentient Wrath, and Fusion Strike, not a reskin of Kullervo's Wrathful Advance, Recompense, and Storm Of Ukko.
  • 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 Kullervo if…

  • Kullervo answers for his sins and the sins of others — that's the Kullervo pitch you want on the roster.
  • Caliban's pitch (“The heir of twin kingdoms ascends”) isn't what you're missing — Collective Curse is.
  • You're buying into Kullervo's passive — kullervo boasts +a percentage Heavy Attack Efficiency and +wind-up% Heavy Attack Wind Up Speed….
Verdict

Both fill the Support / Healer lane. Lean Caliban for Lethal Progeny and Lethal Progeny; lean Kullervo for Collective Curse and Collective Curse. Mission Usefulness is where they split: speed clears (Situational vs Excellent — edge Kullervo).

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.

Kullervo

  • Collective Curse carries mid-mission casts; Storm Of Ukko 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.
  • Dense spawns where Kullervo's cast cadence outpaces gun-only clears.

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?

Caliban
Pull Caliban if…
  • 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.
  • Kullervo 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.

Kullervo
Pull Kullervo if…
  • Collective Curse into Storm Of Ukko is the cast story you want to master — not a random subsume mashup.
  • Recompense and later abilities stay on the frame forever in your builds — you're not looking for a subsume tourist.
  • Caliban's Lethal Progeny loop asks for a different muscle memory than you want to practice.
  • Kullervo rates higher on speed clears (Excellent vs Situational) — that rota is where you actually play.
  • If you only rank one more Warframe to 30 this week, it should be Kullervo.
