Rubico Prime Relics (2026): Where to Farm Every Part
Last Updated on September 18, 2026
Rubico Prime needs 4 relics: Lith T6 for the Barrel (Common slot), Meso R1 for the Blueprint (Rare slot), Lith A3 for the Receiver (Common slot), Axi A9 for the Stock (Common slot). None of them are in the drop tables right now, so the set is vaulted: open relics you already own, watch Prime Resurgence for Varzia’s Aya offer, or buy the parts for platinum.
Relic tables from DE's Public Export; drop locations and vault state from the live drop tables, checked 2026-09-17.
| Part | Relic | Slot | Intact / Radiant | Best place to farm it |
|---|---|---|---|---|
| Barrel | Lith T6 (also Lith S8, Meso Z2, Meso Z3) | Common | 25.3% / 16.7% | not dropping right now |
| Blueprint | Meso R1 (also Meso R2, Meso R3, Meso R4) | Rare | 2% / 10% | not dropping right now |
| Receiver | Lith A3 (also Lith K2, Lith K3, Lith O1) | Common | 25.3% / 16.7% | not dropping right now |
| Stock | Axi A9 (also Lith B5, Lith C8, Lith M3) | Common | 25.3% / 16.7% | not dropping right now |

What Rubico Prime is made of
The item needs a blueprint and 3 components, 4 relic drops in total. The Rare slot is the bottleneck: farm that relic first.
Where each relic drops
None of these relics are in a mission drop table right now: Lith T6, Lith S8, Meso Z2, Meso Z3, Neo H2, Axi M1, Meso R1, Meso R2, Meso R3, Meso R4, Neo R2, Lith A3, Lith K2, Lith K3, Lith O1, Lith W2, Neo K3, Axi T5, Axi A9, Lith B5, Lith C8, Lith M3, Meso E2, Neo P1, Axi D2, Axi L5, Axi P2. Any of them still opens in a fissure of its era if you own one, the parts trade on warframe.market, and Prime Resurgence brings vaulted relics back for Aya.
How to get a vaulted set
- Check Prime Resurgence: when Varzia lists this set, the relics cost Aya and the whole set costs Regal Aya.
- Search your relic inventory (Esc, Void Relic Refinement) for the relics above; old relics still open in any fissure of their era.
- Trade: the built parts sell on warframe.market, and the price check shows what a full set goes for.
- Build once you have everything: 12 hours for the item once you hold the blueprint and every part.
