Understanding Void Fissure Missions
Void Fissures are special versions of standard Warframe missions where the Void has torn through reality, allowing Tenno to crack Relics and earn Prime parts. Every active Fissure is tied to a specific mission type, and knowing the strengths and weaknesses of each one is key to farming efficiently.
Before you enter any Fissure, make sure you have a compatible Relic equipped — the tier must match the Fissure tier (Lith, Meso, Neo, or Axi). Inside the mission, you'll need to collect 10 Reactant from corrupted enemies before extraction to crack your Relic.
Mission Type Breakdown
Capture Fissures
Capture is widely regarded as the fastest Fissure mission type in the game. The mission itself takes under two minutes, and corrupted enemies spawn reliably near the capture target. The short loop makes it ideal for burning through large stacks of Relics quickly. The downside is the mission ends whether your squad is ready or not — you can't stay for a second round.
Exterminate Fissures
Exterminate missions offer a good middle ground between speed and enemy density. You'll have plenty of corrupted enemies to collect Reactant from, and the mission can often be completed in 3–5 minutes. Good for solo play since you control the pace entirely.
Survival Fissures
Survival Fissures are the go-to for extended farming sessions. Each 5-minute rotation awards a new Relic crack opportunity, meaning your whole squad can crack multiple Relics in one continuous run. Life support management is the main challenge, but bringing a Nekros or resource-booster helps significantly. Best run in coordinated squads where everyone brings Radiant Relics of the same type.
Defense Fissures
Defense missions crack a Relic every 5 waves, similar to Survival's rotation structure. Enemy density is high, making Reactant collection easy — especially on lower wave counts. The trade-off is that you're locked into defending a single point, which limits mobility builds.
Excavation Fissures
Excavation is one of the more unique Fissure types. Each extractor you power provides a Relic crack opportunity at the end of its cycle. Managing multiple extractors at once can feel chaotic, but the density of corrupted enemies means Reactant is rarely a problem. Recommended for experienced players comfortable with the mission type.
Interception Fissures
Interception requires your squad to hold capture points, which naturally spreads players across the map. While this can make Reactant collection feel inconsistent, the long rotation structure means multiple cracks per run. Works best with a coordinated squad.
Void Traces: The Other Reason to Choose Carefully
Beyond Relic cracking, Fissure missions reward Void Traces, which are used to refine Relics to higher quality tiers (Exceptional, Flawless, Radiant). The longer you stay in a mission, the more traces you accumulate. Survival and Defense Fissures are therefore excellent for stockpiling traces alongside parts.
Quick Reference Table
| Mission Type | Speed | Cracks Per Run | Best For |
|---|---|---|---|
| Capture | Very Fast | 1 | Burning Relic stacks |
| Exterminate | Fast | 1 | Solo farming |
| Survival | Slow (extended) | Multiple | Coordinated squads |
| Defense | Moderate | Multiple | High enemy density |
| Excavation | Moderate | Multiple | Experienced players |
Final Recommendations
- Fast farming solo: Capture or Exterminate
- Coordinated squad targeting a specific part: Survival or Defense with 4× Radiant Relics
- Stockpiling Void Traces: Long Survival runs
- New players learning the system: Exterminate — easy pace, straightforward layout
Understanding which mission type fits your goal is the first step toward becoming an efficient Relic farmer. Once you've mastered Reactant collection and Relic selection, the Void's rewards are yours for the taking.
