Kullervo vs Uriel

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 Uriel's Demonium loop.
  • You're buying into Kullervo's passive — kullervo boasts +a percentage Heavy Attack Efficiency and +wind-up% Heavy Attack Wind Up Speed….

Pick Uriel if…

  • You're sold on Uriel's fantasy (To fight as the Heretic of Xata is to have demons at your back) more than another Support / Healer option.
  • You'd rather build around Demonium than live in Kullervo's Collective Curse loop.
  • You're buying into Uriel's passive — uriel commands, empowers, and protects three unique demons.
Verdict

Both fill the Support / Healer lane. Lean Kullervo for Collective Curse and Collective Curse; lean Uriel for Demonium and Demonium. 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.

Uriel

  • Demonium carries mid-mission casts; Brimstone is the density payoff.
  • Fights where Heat stays painted on packs so Uriel's Affinity-Range Strength passive stacks.
  • Dense spawns where Uriel's cast cadence outpaces gun-only clears.

Mod Scaling Focus

Kullervo

DUR
Extends channeled / timed effects — often comfort on Kullervo if the kit leans on buffs or zones.
RNG

EFF
Keeps ability uptime comfortable, especially on longer Steel Path missions.

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.

  • Uriel's Demonium 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.
