Hardened dragon bonemeal detail.png

Hardened dragon bonemeal is an item that can be used to train Prayer at the Ectofuntus. To create the bonemeal, players must grind hardened dragon bones on the top floor by dropping them in the hopper and turning the valve (giving 1 Prayer experience in the process). The player can then empty the bin to receive the bonemeal. The bonemeal will automatically be put in a pot, it is not required to bring one.

Combined with a bucket of slime, it can be used to worship the ectofuntus, giving 4 times the normal Prayer experience, as well as 5 ecto-tokens. No pots or buckets are returned when doing so.
