Before you go

Unlock Ukko on the Void Star Chart.
Bring a loadout that can complete Capture and reach extraction reliably.
Set Neo C11 as the target and leave room in your relic inventory.

Farming steps

Launch Ukko and follow the objective marker to the Capture target.
Complete the Capture objective, then proceed to extraction.
Finish the mission and inspect the reward for the full name Neo C11.
If a different relic was awarded, start another Ukko run and check again.
When you have Neo C11, select it for a matching Void Fissure mission.
Collect reactant during the fissure and complete its objective to open the relic.
Choose the Citrine Prime Chassis blueprint from the reward selection if it appears.

Ukko can award Meso or Neo relics, so verify the tier and identifier rather than keeping any relic from the run.
A relic drop only starts the Prime part hunt; opening it does not guarantee the Chassis blueprint.

Repeat, collect and use

Ukko is repeatable without a stated weekly limit. Repeat Capture runs until Neo C11 is obtained; open more Neo C11 relics only if the Chassis blueprint is still missing.

Common mistakes

Stopping after any Neo relic: check that the reward is specifically Neo C11.
Expecting the Chassis blueprint from Ukko: the node awards relics, while fissures produce relic rewards.
Treating one relic opening as guaranteed: continue opening the target relic while the blueprint remains needed.

When to stop or switch

Stop Ukko runs when Neo C11 is in inventory. Stop opening relics when the Chassis blueprint is acquired, or switch to another Citrine Prime part if that is the remaining need.
