Crystal Extractor

Troubleshooting

Crystal Extractor Not Working?

Don't panic. If your extractor isn't collecting resources, it's usually one of these 5 simple reasons.

Common Symptoms

  • No XP Drops: You aren't seeing Farming/Sailing XP.
  • Empty Bank: No resources are appearing in your bank.
  • "Can't Build Here": You can't place the facility.

The 5-Step Fix Checklist

Go through these steps in order to solve 99% of "not working" issues.

  1. Check Your Sailing Level: You strictly need Level 80 Sailing to build and operate it. Boosting works for building, but you might need the level to operate it efficiently.
  2. Is it Charged? The Crystal Extractor requires Crystal Shards to function. Check if it has run out of charges.
  3. Is Your Bank Full? If your bank is completely full, the extractor cannot deposit resources and will stop working.
  4. Are You in a Valid Zone? The extractor only works in specific maritime zones (e.g., Deep Sea, Coastal). It won't work while docked at a port.
  5. Did You Toggle it On? Right-click the facility and ensure it is set to "Active".

"Crystal Catcher" vs "Crystal Extractor"

⚠️ Clarification: There is no item in OSRS called a "Crystal Catcher".

If you are searching for this, you are likely confusing two items:

Understanding the Timer

The Crystal Extractor works on a passive timer, similar to Farming patches or Bird Houses.

The "Tick" Rate

It attempts to harvest a resource every 5 minutes (approx. 500 ticks).

Offline Gains

Yes, it works while you are logged out! However, the internal buffer fills up after 6 hours. You must log in to "empty" it to the bank (automatic upon login) to reset the timer.

Notification

Use the Watchdog Plugin to get an alert when the 6-hour buffer is full.

Troubleshooting FAQ

Why can't I build it on my Sloop?
The Sloop has limited "Large Facility" slots. Ensure you haven't already filled your large slot with a Cannon or Spirit Tree. You may need to remove one first.
Does it work in PvP worlds?
Yes, but if your ship is sunk, you may lose the stored resources in the buffer that haven't been banked yet.
