A Prime set is assembled, not opened
The instinct when you want a Prime Warframe is to open relics. That produces a pile of parts you did not need, most of which you will sell for ducats. The players who finish sets quickly do something different: they treat the set as a four-piece jigsaw and go after the specific pieces they are missing.
That requires knowing what a rare part actually costs in relics, which is what the tables below are for.
The odds, and the cost per part
| Quality | Traces | Rare chance |
|---|---|---|
| Intact | 0 | 2% |
| Exceptional | 25 | 4% |
| Flawless | 50 | 6% |
| Radiant | 100 | 10% |
Converted to the number that matters — how many relics it takes to see one rare:
| Quality | Relics, average | Relics for 90% confidence |
|---|---|---|
| Intact | 12.9 | 28.5 |
| Exceptional | 6.6 | 14.1 |
| Flawless | 4.6 | 9.3 |
| Radiant | 2.9 | 5.5 |
Read the two right-hand columns together. If you want a likely drop, 2.9 Radiant relics. If you want to be almost certain, 5.5.
A Prime set usually contains two or three rare parts spread across different relics. Multiply accordingly: two rares is roughly six Radiant relics on average, three rares roughly nine. Those are expectations, not guarantees, and the 90 percent column is the honest planning number.
The void fissure guide explains why refining is a flat-rate purchase with no optimal tier, and why a mixed squad usually beats an all-Radiant one.
Reading the drop table before you farm
Every relic shows its contents, and the practical skill is deciding whether a relic is worth opening at all.
Check whether the rare is the part you need. A relic whose rare drop is a part you already own is a ducat source, not a farming target.
Check how many of the six items you still need. A relic where you need four of six is efficient; one where you need only the rare is a long shot.
Check whether the relic is vaulted. Vaulted relics cannot be farmed, only spent from your stock, so they are a finite resource. Do not burn a vaulted relic on a set you do not intend to finish.
Check era coverage. Lith, Meso, Neo and Axi correspond to different mission level bands. Keeping one or two of each era equipped means any fissure you land on pays out.
The squad rule, and how to exploit it
Every equipped relic contributes to the pool, and each player picks one item from the combined results. A four-player squad therefore offers four reward sets per run.
Two consequences:
Never run fissures alone if you can help it. The reward pool scales with squad size, and a solo run produces one set.
Bring different relics from the same era. Four copies of the same relic gives four shots at the same rare. Four different relics of the same era gives a pool covering four different sets, which is strictly more useful for assembling anything.
If you are hunting one specific part, coordinate: everyone brings the same relic and you all pick the rare if it appears. That is the one case where stacking identical relics is correct, and it is how organised groups turn a 10 percent chance into a 34 percent squad chance per run.
Ducats, and the parts you do not need
Prime parts you do not need convert to ducats at a relay kiosk. Ducats buy from Baro Ki’Teer, whose stock rotates and who occasionally brings relics nobody else has.
Note the direction: you convert prime parts to ducats, not relics. An intact relic cannot be turned into ducats, which is the mistake that leaves players holding fifty relics and no ducats.
The decision on a duplicate part is ducats versus platinum. Popular parts sell for more platinum than their ducat value implies; unpopular ones are worth more as ducats. The trading guide covers pricing the ones worth selling.
Aya, Regal Aya and the Vault
Items retired from drop tables go to the Prime Vault. Since Prime Resurgence, vaulted items return periodically through Varzia at Maroo’s Bazaar.
Varzia accepts two currencies:
- Aya — earned in game, spent on vaulted Prime parts and relics.
- Regal Aya — the paid equivalent, bought with real money, for the same vendor.
During a Resurgence event, the unvaulted frame and weapons are also re-added to drop tables through new relics, which means you can farm them for free while the event runs. Doing so is strictly cheaper than buying with Regal Aya, and the window is the whole reason to track Resurgence dates.
Baro Ki’Teer is the third route: he periodically brings relics that only he offers, and when he leaves those items return to the Vault. That makes a Baro weekend the only chance to get certain relics for ducats rather than platinum.
The habit that finishes sets
Keep a spreadsheet or a checklist, and record what you own. Almost every player who is “unlucky with relics” is actually opening relics whose rare they already have.
The loop that works:
- Identify the missing piece for a set you actually want.
- Find which relics contain it and which era they are.
- Run that era in a squad, everyone bringing the same relic if the group is coordinated.
- Refine only when traces are abundant, because void trace capacity is capped by mastery rank and overflowing traces are wasted.
- Convert every unwanted part to ducats immediately, rather than letting them pile up.
For the Lich and Sister weapons that use Requiem relics instead, the Kuva and Tenet weapons guide covers the separate conversion rules. The platinum guide explains when buying a set outright beats farming it.
