Where to build a Arc Furnace: Equatorial Band

The game's own requirement line, then the conditions of the first stage (possible) and of the planet or star it goes around (placement_rules).

The planet or star
  • Cannot build on planets that have unresearched anomalies discovered by us or any other Empire.
  • Planet class: Molten World
  • Cannot build due to existing Megastructure.
  • When from (Controlled by the AI)
    • solar system
      • count system planet
        • Count at least 8
The system and the empire
  • When from (Not: Nomadic empire)
    • The system has a starbase
    • Cannot build outside Empire borders.
  • Otherwise
    • Requires the system is on a Wayline with a Wayport or Wayhold.
  • When Not: any starbase in system (Is waystation starbase; owner? (Is the same as: the scope that called it))
    • Cannot build in systems that have not been surveyed.
  • Cannot construct in the same system as an existing Dyson Sphere
  • Cannot construct in the same system as an ongoing Dyson Sphere construction
  • Cannot construct in the same system as an existing Arc Furnace
  • We can not sustain more than … Arc Furnaces at a time

Arc Furnace: Equatorial Band stages

Cost lines with a condition apply only to the empires it names (bio-ship empires pay food instead of part of the alloys).

How it's counted

Totals in the head count only the costs every empire pays: 7,500 Unity.
