Erchius Ghost

Erchius Ghost will appear on Moons if you carry any Erchius in your inventory. It will relentlessly chase you. The more fuel you have, the faster the Ghost will be.

If a Ghost is too close to you, you will start losing health and/or energy. This can be deadly. Throwing away fuel won't stop the Ghost.

Countermeasures

 * By equipping Erchius Buddy will make you immune: new Erchius Ghosts won't spawn, and if the Ghost already exists, it won't harm you even if you stand near it.
 * Ghost Lantern (a rare flashlight) also protects you from Ghost, but only when you carry it.
 * Ghost Shield (EPP Augment) can be inserted into your EPP to give you immunity. At later game, you can place the Ghost Shield into your Atmospheric Filter or Atmospheric Regulator to project this immunity across your entirr base - which is convenient if your base is on the Moon.
