Trivia[edit | edit source]

  • 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 197,792,319 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 173,068,279, but it would take far longer to do so.
    • Cremating the bones would cost 625,471,654, and would additionally give 10,427,545 Firemaking experience.
    • Simply burying the bones would cost 692,273,114.
