Lightless



Lightless Sphere planets are stark, nigh-impregnably dark and full of danger if you don't bring ample light.

These worlds are the sole source of Effigium Ore. They have a stronger Erchius Ghost, who will follow the players if they mined any Erchius or Effigium Ore.

They contain numerous valuable resources, but are never a bright and cheery place.

Unbreachable Darkness
Being on the Lightless planet inflicts "Unbreachable Darkness" debuff (you can only see a few blocks away, no matter how many Torches you place). You will need some form of immunity to it, such as Darklight Blossom or Darkness Shield.
