Frost dragon bonemeal is an item that can be used to train Prayer at the Ectofuntus. It is created by taking an empty pot along with Frost dragon bones to the top floor of the ectofuntus and using the bones on the grinder. Along with a bucket of ectoplasm, players may use a pot of bonemeal to make 5 ecto-tokens. The bones used in the bonemeal give 4 times the prayer experience when used to worship the Ectofuntus.
