Kullervo vs Lavos

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

TL;DR — Quick Pick

Pick Kullervo if…

  • Kullervo answers for his sins and the sins of others — that's the Kullervo pitch you want on the roster.
  • You'd rather build around Collective Curse than live in Lavos's Transmutation Probe loop.
  • You're buying into Kullervo's passive — kullervo boasts +a percentage Heavy Attack Efficiency and +wind-up% Heavy Attack Wind Up Speed….

Pick Lavos if…

  • You want the squad gap filled by Lavos's vibe — The serpents of Lavos encourage him as he transmutes the battlefield.
  • You'd rather build around Transmutation Probe than live in Kullervo's Collective Curse loop.
  • You value Lavos's orb-efficiency passive for longer ability spam on dense holds.
Verdict

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

When Each Shines

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.

Lavos

  • Transmutation Probe carries mid-mission casts; Catalyze is the density payoff.
  • Long holds where energy comfort matters — Lavos's loop stays online without babysitting orbs.
  • Missions that reward committing to Lavos's full ability loop instead of dabbling.

Mod Scaling Focus

Kullervo

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

Lavos

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 Lavos’s Strength-scaling abilities.
DUR
Extends channeled / timed effects — often comfort on Lavos if the kit leans on buffs or zones.
RNG

EFF

Who Should You Pull?

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.
  • Lavos's Transmutation Probe 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.

Lavos
Pull Lavos if…
  • Energy / health orb rooms are common in your rota and Lavos gets more mileage out of every pickup.
  • Squad comps where someone has to own tile clear alone — Lavos is the frame you trust for that job.
  • Kullervo can stay on the shelf; Lavos is the one you'll actually Forma twice.
  • Even after Helminth, Vial Rush and later abilities are still the reason Lavos earned potato.
  • Your endgame loadout screen should show Lavos before it shows another same-role experiment.
