Warframe · Kullervo

No shields. All crit.

Kullervo answers for his sins with a knife. He teleports, paints melee crit, chains damage across a cursed pack, and wears Overguard because he was not given shields.

Your first endgame-capable version.

Best for: Steel Path Star Chart, Circuit, first Archon. Helminth is the next card.

High Strength Wrathful Advance. Flat melee crit until everything is red. This is 2026 Kullervo. This is the peak you can run the day Steel Path unlocks — galvanized / arcanes, no Helminth.

Key mistakes

Never inverting tap/hold on 1
Default tap is a heavy-teleport onto a target. Invert so tap is 'go there.' Settings, once.
Treating him like a shield-gate frame
0 shields. Overguard or bleedout. Recast 2.
Stacking crit chance on the melee and skipping crit damage
Wrathful is the chance. Organ Shatter and violet shards are the damage.
