Territory Purification is one of the main ways of earning Stardust[]
You need Eclipse Cortexes - PvE or Chaotic Cortexes - PvP, to perform Territory Purification.
The limit is 40 Cortexes per week, with reset on Monday.
The minimum Territory Purification event duration is 3 minutes, this increases when more Cortexes are used.
| Cortex Level | Starchrom | Monster Level | Monster Waves | Recommended Players | Number of Elite Enemies |
|---|---|---|---|---|---|
| 1 | 70 | 15 | 2 | 2 | 1 |
| 2 | 85 | 25 | 2 | 2 | 1 |
| 3 | 100 | 35 | 2 | 2 | 1 |
To start Territory Purification, you need to build a Stardust Resonant Filter - go into the Build menu, Facilities - 4th tab, Function Facility.
It's highly recommended to build defenses around the Resonant Filter, as the enemies will run towards it to damage it.
If you are on a PvP Server, your territory will enter the Chaotic State, allowing the other players to attack it.
