UmbraTrackerVoid Fissure duration and rates, measured
Common wisdom says each relic era has its own fissure duration. Our log says otherwise. Every figure below comes from our own automatic recording, and the page recomputes itself.
Duration is random, and identical for every era
Fissure lifetime is drawn uniformly between 60 and 120 minutes. We observed 61 distinct whole-minute values across the range, with a median of 90 minutes, and the same spread for every era. So knowing the era tells you nothing about how long a fissure will stay.
How many appear, and how many are active
About 498 fissures per day open across all eras, 29879 recorded over 60 days. At any moment the number active is 33 (8.6%), 34 (8.5%), 28 (8.3%).
Per era
| Era | Logged | Per day | Duration | Nodes |
|---|---|---|---|---|
| Lith | 6524 | 108.7 | 60–120 min | 40 |
| Axi | 6485 | 108.1 | 60–120 min | 53 |
| Meso | 5048 | 84.1 | 60–120 min | 43 |
| Neo | 4975 | 82.9 | 60–120 min | 38 |
| Requiem | 3664 | 61.1 | 60–120 min | 8 |
| Omnia | 3183 | 53.1 | 60–120 min | 6 |
Steel Path and Railjack share
Steel Path accounts for 35.4% of fissures and Void Storms for 28.9%.
When the next fissures spawn
Fissures do not spawn at random moments. Each era (Lith, Meso, Neo, Axi, Requiem, Omnia) runs its own chain in each mode: a new wave of 1 to 3 fissures appears 4 min 30 before the last active fissure of that era expires, in 100% of the waves we logged, so there is always at least one of each era. A wave never contains two nodes of the same planet (never two missions of the same type for Requiem, which has a single location), and a node already active cannot be drawn again. Each planet of the era joins the wave with a fixed chance, reduced in proportion to the nodes it still holds, which is why an Omnia planet drops from about 69% to 33% while one of its two nodes is running. The tracker uses this to show the time of the next wave and the odds of each mission type.
Method and limits
Based on 29879 fissures logged automatically over 60 days from the public world state. Timestamps are quantised to the minute upstream, so we do not claim sub-minute precision. These are server-side parameters Digital Extremes can change at any update.
