What Are Void Fissures?

Void Fissures are special mission nodes that appear on the Star Chart, marked with a distinctive golden tear icon. They work like regular missions — Defense, Survival, Capture, etc. — but with one key difference: they are infected by Void energy, which causes corrupted Orokin enemies to appear alongside the normal faction. These corrupted enemies drop Reactant, the resource you need to crack your Relic.

Completing a Fissure mission with a Relic equipped rewards you with a Prime part or Prime blueprint — components needed to build powerful Prime versions of Warframes and weapons. This is the primary way most players acquire Prime gear.

Step 1: Get a Relic

Before you can participate in a Fissure run, you need a Relic. Relics come in four tiers, each tied to a specific Fissure type:

  • Lith — Dropped in early-game missions; used in Lith Fissures
  • Meso — Mid-game content; used in Meso Fissures
  • Neo — Mid-to-late game; used in Neo Fissures
  • Axi — Endgame content; used in Axi Fissures

Relics are dropped by enemies, rewarded from mission completions, earned via Syndicate standing, and purchased with various currencies. As a beginner, focus on Lith Relics first — they're easy to find and crack in accessible missions.

How to equip a Relic: On the mission selection screen for any active Fissure, you'll see a prompt to select a Relic. Choose one that matches the Fissure tier shown. You cannot bring a Meso Relic into a Lith Fissure.

Step 2: Collect 10 Reactant

Once inside the Fissure mission, you'll notice a Reactant counter in the bottom right of your HUD. Corrupted enemies (glowing Orokin soldiers and drones) drop small orb-like pickups called Reactant. Simply walk over them to collect them.

You need exactly 10 Reactant before the mission ends (or before the next rotation in Survival/Defense). Without 10 Reactant, your Relic will not be cracked and you'll receive no Prime reward.

Tips for collecting Reactant:

  • Kill corrupted enemies as soon as they appear — they're marked with a gold icon on your minimap.
  • In a squad, Reactant is collected individually — don't rely on teammates to get yours for you.
  • In Survival missions, make sure you hit 10 Reactant before the 5-minute rotation mark, or you'll miss that round's crack.

Step 3: Choose Your Reward

After collecting 10 Reactant and completing the mission objective, you'll reach the reward screen. Here's what happens:

  1. Your Relic is "cracked open" and one of its possible rewards is revealed to you.
  2. In a squad, you see all four players' rewards displayed simultaneously.
  3. You choose one reward from the four options — it can be your own or a squadmate's.
  4. Every player who picks the same reward as another gets a duplicate — this is fine, duplicates can be used for crafting or sold to Baro Ki'Teer for Ducats.

This sharing mechanic is what makes squads so valuable. If someone in your group cracks a rare Prime part you need, you can take it even if your own Relic didn't reveal it.

Understanding Prime Parts and Ducats

Prime parts come in categories: Neuroptics, Chassis, Systems (for Warframes) and Barrel, Receiver, Stock (for weapons), plus Blueprints for each. You need all components to build the full Prime item in your Foundry.

Duplicate or unwanted Prime parts can be sold to Baro Ki'Teer (the Void Trader) for Ducats, a special currency he uses to sell exclusive weapons, mods, and cosmetics. Never discard Prime parts — always sell them to Baro instead.

Quick-Start Checklist

  1. ✅ Reach the Star Chart node where Lith Fissures are active (check your Navigation screen)
  2. ✅ Have at least one Lith Relic in your inventory
  3. ✅ Select the Relic at the mission screen before launching
  4. ✅ Kill corrupted enemies and collect 10 Reactant before extraction
  5. ✅ Choose your reward on the end screen
  6. ✅ Repeat until you have all the parts for your first Prime build!

What's Next?

Once you're comfortable with the basics, explore Relic refinement (upgrading your Relics with Void Traces for better drop odds) and coordinated Radiant squads for targeting specific rare parts. The Void rewards preparation — the more you understand its systems, the more efficiently you'll build your Prime collection.
