Some people see Kullervo, the seven-time criminal of the Orokin Empire, as a folk hero, while others see him as a villain. It takes some careful planning and considerable grinding to achieve this blade-pierced Warframe, which is modeled by the Finnish Kalevala, but it's well worth the wait thanks to his teleportation ability and storms of daggers!
cultivating Kullervo
You had to have unlocked Duviri by finishing the plot of "The Duviri Paradox" before you may get Kullervo. Although Kullervo is not part of that narrative, he sometimes shows up as an objective in the Duviri Experience and the Lone Story's Anger, Sorrow, and Fear spirals. Kullervo's Hold, his floating island prison, is visible in the Anger, Sorrow, and Fear spirals of the Duviri Experience even though battling him isn't listed as a goal.
Each spiral lasts for two hours and moves through the following emotions: Joy, Anger, Envy, Sorrow, and Fear. The beginning of Sorrow is the ideal place to start a long grinding session since you'll have two spirals to grind Kullervo before needing to wait.
- Wait until Duviri is in the Anger, Sorrow or Fear spiral
- Access the Duviri Experience
- You should see Kullervo’s Hold as a round island at the bottom of the map
- Build up some decrees, as Kullervo can be quite tough to fight, especially if you don’t yet have the intrinsics that improve your ability to summon your Warframe into Duviri itself
- When you’re ready, travel to Kullervo’s hold and bribe the Warden overlooking the circular arena with 5 pathos clamps to let you fight Kullervo
- Travel down into the arena and wait for Kullervo to emerge from his cage
- Once you have defeated Kullervo, trigger the Orowyrm and defeat it. You will be rewarded with Kullervo’s Bane when you extract
- Trade Kullervo’s Bane in with Acrithis in the Dormizone to buy the blueprints for Kullervo. You’ll need 42 Kullervo’s Bane to purchase all the pieces
Kullervo Building
To create Kullervo, you need to harvest many Duviri-specific resources in addition to purchasing Kullervo's Bane. Since this might take some time, here is a short list:
- 10 pathos clamps, obtained by defeating an Orowyrm
- 50 Lamentus, dropped by enemies in Duviri
- 125 Nacreous Pebbles and 360 Ariette Scales, obtained through the maw feeding fishing activity
- 100 Aggristone — look out for Aggristone Formations or gain them through Duviri objectives
- 50 Tasoma Extract from caves
- 100 Saggen Pearls, found mostly in buildings and settlements
- 100 Conla Sprouts, found beside water, but particularly next to the pools in the Lunaro Court area
- 100 Kovnik, found across Duviri- 75 Runemarrow, gained through smashing deposits in the Undercroft
- 100 Eevani, found in the Archarbor and Amphitheater areas
- 200 Ueymag, found in Kullervo’s Hold (during Anger, Fear and Sorrow spirals) and the Chamber of the Muses
Although it may seem daunting at first, you'll quickly get adept at blink teleporting since you'll be touring Duviri to accrue decrees and visiting Kullervo's Hold to harvest Kullervo's Bane.
