EVE Online: Legion Patch Notes - Sovereignty / Equinox Upgrades

EVE Online's Legion expansion, set to launch on 27 May 2025, is the game's sixth full expansion since the return of the content format in November 2022. As usual at this point I intend to go through the patch notes and bring in some context from other sources. The fifth subject addressed are sovereignty/Equinox upgrades.

The Legion in Focus dev blog gave a summary of the upgrades arriving in the expansion.

Meanwhile in nullsec, sovereignty continues to evolve. Legion introduces more flexibility and customization with three new categories of upgrades. New resource conversion upgrades give you more control over your resources, with the ability to generate workforce from power and vice versa. New system-wide modifiers let you lean into the strengths of your doctrine, offering bonuses to scanning, targeting, and specific combat styles.

I'm not exactly sure why the developers waited so far down the patch notes to discuss these new features. The first change involves installing upgrades in sovereignty hubs.

Sovereignty / Equinox Expanded

• Upgrades that you can install in a sovereignty hub are no longer limited by the maximum potential power in the solar system. This means that you could for example, have all 7 mineral type upgrades installed now, and swap between them through re-prioritizing or offline/onlining them, rather than needing to destroy them to install new ones.

The next comes additional exploration options in player-held sov systems.

New Exploration Upgrades

We are introducing a new sov upgrade that can generate undetected relic and data signatures.

• Exploration Detector 1, 2 and 3.
• These three tiers of Exploration Upgrades will have a combination of data and relic sites and will be available from the Angel Cartel, Blood Raiders, Guristas Pirates, Sansha Nation, Serpentis and Rogue Drone factions.
• These exploration upgrades have a guaranteed chance to spawn several exploration sites between 0 and 5 jumps from the solar system where the upgrade is installed.
• Exploration sites spawned from the sov upgrades all have a small chance to escalate to a brand-new data and relic escalation with the potential for high rewards.
• Exclusive rewards from the data escalation include blueprint copies for the powerful new “Xarasier” storyline modules for micro jump drives, reactive armor hardeners, ancillary shield boosters and armor repairers, the new hacking focused ‘Wedge’ implant set and the triplot scan acquisition array.
• The higher tier upgrades have an increased number of sites and faster respawn times.

The expansion will also introduce additional upgrades to generate colony resources.

Resource Generation Upgrades

We are introducing two new sov upgrades that can generate colony resources by utilizing other colony resources.

• Workforce Mecha-Tooling upgrade, available in 3 tiers, which costs power and generates workforce.
• Power Monitoring Division upgrades, available in 3 tiers, which costs workforce and generates power.
• Upgrades are mutually exclusive and it’s not possible to have both workforce and power upgrades installed at the same time.

And finally Legion grants the opportunity to bring Abyssal deadspace effects to player-owned null sec.

System Effect Generator Upgrades

We are introducing a new type of upgrade with Legion which players can install in sovereignty hubs to provide a set of bonuses to all ships in the solar system. The upgrades have a very low daily upkeep but a very high onlining cost to discourage swapping them out and toggling them on/off frequently.

• Electric Stability Generator
• This generator produces system-wide effects similar to those encountered in Electric environments within Abyssal Deadspace.
• All ships in system: 25% bonus to Capacitor recharge rate, +25% targeting range and Directional Scanner range.
  
  
• Exotic Stability Generator
• This generator produces system-wide effects similar to those encountered in Exotic environments within Abyssal Deadspace.
• All ships in system: +25% scan resolution, +2 AU/s warp speed.
  
  
• Gamma Stability Generator
• This generator produces system-wide effects similar to those encountered in Gamma environments within Abyssal Deadspace.
• All ships in system: +5% Shield HP, 5% Shield Booster Effectiveness, +10% Capacitor capacity.
  
  
• Plasma Stability Generator
• This generator produces system-wide effects similar to those encountered in Plasma environments within Abyssal Deadspace.
• All ships in system: +5% Armor HP, 5% Armor Repairer Effectiveness, +10% bonus to the benefits of overloading modules.
