Toxic Skies

Toxic Skies is a Bukkit plugin that makes the world a harsher and more dangerous place. Players are forced to survive underground or else be destroyed by the elements. Toxic Skies adds the following game mechanics:

  1. Players who get too close to the surface get periodically poisoned by the surface air.
  2. Staying above ground without protection will result in death after about two minutes.
  3. Pumpkins work like gas masks. Wearing one above ground prevents damage for a time.
  4. The weather is always storming. Monsters never catch on fire and visibility is reduced.

Compatible with Multiverse.


  1. Put .jar file in the Plugins directory.
  2. Start the server to generated a default config file.
  3. Update the config.yml file to set which worlds you want made toxic.
  4. Restart or reload the server.
