Kullervo fights with daggers and hoards other people's sins: Collective Curse marks a crowd, Wrathful Advance teleports him into someone's face with a guaranteed crit. A Duviri frame with a temper.
Can you buy Kullervo for platinum

In short, yes, Kullervo costs 325 platinum in the Market and arrives fully built with a free slot.
- Price. 325 platinum for a built Kullervo with a slot for it.
- Mastery. It ticks the same whether the frame was bought or built, so buying saves time, not rank.
Is there a Kullervo Prime

No, there is no Prime version of Kullervo yet. Primes usually arrive about two years after the original and strictly in order, so the turn will come, but nobody can promise a date.
Where the blueprints come from

Kullervo's blueprints are sold by Acrithis in the Dormizone for Kullervo's Bane: 15 for the main one and 9 per component, 42 in total. The Banes drop from beating the Kullervo boss and from completing the Spiral, meaning killing the Orowyrm, in Duviri. He shows up on the island called Kullervo's Hold, which only spawns on Anger, Sorrow and Fear spirals in The Duviri Experience. Talk to The Warden and take the fight in the flooded arena.
What it is built from

The Foundry wants four runs: three components first, the final assembly after. Components run in the Foundry at the same time, so from the first click to a finished frame it is roughly 84 h: twelve for the parts and 72 for the Warframe itself.
| Blueprint | Credits | Time | Resources per build |
|---|---|---|---|
| Chassis | 15 000 | 12 h | Nacreous Pebble x125, Kovnik x100, Rune Marrow x75, Ueymag x100 |
| Neuroptics | 15 000 | 12 h | Lamentus x50, Tasoma Extract x50, Saggen Pearl x100, Connla Sprout x100 |
| Systems | 15 000 | 12 h | Aggristone x100, Eevani x100, Ariette Scale x360, Ueymag x100 |
| Kullervo | 30 000 | 72 h | Kullervo Neuroptics x1, Kullervo Chassis x1, Kullervo Systems x1, Pathos Clamp x10 |
Where to farm the resources

Look at Pathos Clamp first. The recipe asks for 10, and you will have to go and get it deliberately. Duviri, from the Orowyrm fight at the end of a Circuit or Undercroft run. Everything else accumulates while you play and needs no special trip.
| Resource | Where it drops |
|---|---|
| Pathos Clamp | Rewarded upon defeating the Orowyrm in Duviri |
| Nacreous Pebble | Maw Feeding in The Duviri Experience |
| Kovnik | Duviri |
| Rune Marrow | The Undercroft in Duviri |
| Ueymag | Duviri |
| Lamentus | Duviri |
| Tasoma Extract | Duviri |
| Saggen Pearl | Duviri |
| Connla Sprout | Duviri |
| Aggristone | Duviri |
| Eevani | Duviri |
| Ariette Scale | Maw Feeding in The Duviri Experience |
Is Kullervo worth building
Kullervo carries his own guilt as a resource: Wrathful Advance teleports him into a crowd with guaranteed critical hits.
The numbers look like this: no mastery rank requirement, roughly 84 hours from the first foundry press to a finished frame, and 75 000 credits across all the builds together.
A melee frame with almost no ramp-up. You need Duviri to get him, and Duviri is its own learning curve.
Every other frame is broken down the same way, the full list lives in the guide to all Warframes.
