Rule 1: Don't be toxic, be it for personal conversations or for other people's theories.
Rule 2: Be reasonable with posts. If you see 5 posts about a new event or item being found (for example, Bad Juju or Outbreak Perfected), don't make another one. Please.
Rule 3: Spoilers, spoilers, spoilers! Make sure you format your posts correctly if there's spoiler based content. That's any new item that's shown up IN GAME for the first few days OR any datamined content. If someone finds Gjallarhorn, don't ruin the surprise!
Rule 4: Have fun!
