Swarm Clusters in Er’Yozun
Every hostile in Er’Yozun is a Swarm Cluster, a level 24 Swarm interceptor with a strength of 191,377. Each kill pays 51 to 69 Frequency Modulators. The same level 24 Swarm Cluster also spawns in Lahrel, the other level 24 Swarm system at warp 22, so the two make an easy pair to alternate between when the targets run low.
Frequency Modulators are the special currency some ships use to upgrade their components. If you are spending them, the Frequency Modulator Cost Efficiency research makes each one go further.
Where to find Swarm Clusters around level 24
Swarm Clusters form a ladder, starting at level 15 in Andvaris and Kohva (warp 13) and climbing to level 46. The Frequency Modulator payout rises fast with each step. If Er’Yozun is too easy or too hard, these are the next systems up and down the chain.
| Swarm Cluster level | Systems | Warp | Strength | Frequency Modulators per kill |
|---|---|---|---|---|
| 20 | Beta Vordunn (warp 15), Idran (warp 25) | 15 to 25 | 74,784 | 18 to 24 |
| 22 | Klaiz | 15 | 113,759 | 30 to 41 |
| 24 | Er’Yozun, Lahrel | 22 | 191,377 | 51 to 69 |
| 26 | Alpha Horunia, Sayo | 22 | 359,607 | 86 to 116 |
| 28 | Ortek, Redmond | 22 | 605,484 | 145 to 196 |
| 30 | Fontaine, Von | 23 | 954,985 | 245 to 331 |
Level 26 and 28 Swarm Clusters need the same warp 22 as Er’Yozun and pay roughly 1.7 and 2.8 times as many Frequency Modulators, so step up as soon as your ship can win those fights.
Planets in Er’Yozun
Er’Yozun has 3 named planets: Destora, Maur and a planet that shares the system’s name, Er’Yozun. There are no mining nodes or housing containers, so the Swarm Cluster is the only reason to stop here.
Is Er’Yozun worth the trip?
Only for Frequency Modulators. Er’Yozun and Lahrel are the level 24 step on the Swarm Cluster ladder, reachable at warp 22 with no entry cost. Players around level 24 will find it a quick farm. Once your ship handles level 26 or 28 Swarm Clusters, Alpha Horunia, Sayo, Ortek and Redmond pay more for the same warp.
