Makes drifters spawn only underground, and with very low artificial light level, or at least wherever natural light would not have been able to reach.

Based off 'Drifter Overhaul Mod' by Grifthegnome. I just changed one of the values, "blocklight" -> "maxlight" as well as the maxLightLevel value.

Changes:

[
  {
    "op": "replace",
    "path": "/server/spawnconditions/runtime/lightLevelType",
    "value": "MaxLight",
    "file": "game:entities/land/drifter.json",
    "side": "Server"
  },
  {
    "op": "replace",
    "path": "/server/spawnconditions/runtime/maxLightLevel",
    "value": 4,
    "file": "game:entities/land/drifter.json",
    "side": "Server"
  },
  {
    "op": "replace",
    "path": "/server/spawnconditions/runtime/maxYByType/*-normal",
    "value": 0.98,
    "file": "game:entities/land/drifter.json",
    "side": "Server"
  }
