Hardened dragon bones provide 18 souls for the Well of Souls when used as input for a Greater communion ritual.

    • Additionally, the first bone would take them straight to level 5 Prayer.
  • Using the ectofuntus would cost 276,415,929, but it would take far longer to do so.
  • Cremating the bones would cost 1,746,613,754, and would additionally give 10,427,545 Firemaking experience.
