Trivia

• Hardened dragon bones were changed to their current name on 10 April 2017 due to gemstone dragons sharing the same bone drop.
• There are multiple ways to use hardened dragon bones to get from 1-99 Prayer:
  • A player choosing to use a gilded altar with lit burners and no other experience boosts would spend 435,412,065 if all the bones were bought at the current medium price on the Grand Exchange.
    • Additionally, the first bone would take them straight to level 5 Prayer.
  • Using the ectofuntus would cost 380,985,557, but it would take far longer to do so.
  • Cremating the bones would cost 1,563,335,171, and would additionally give 10,427,545 Firemaking experience.
  • Simply burying the bones would cost 1,523,942,225.
