Bat bonemeal is an item that can be used to train Prayer at the Ectofuntus. To create the bonemeal, players must grind bat bones on the top floor by dropping them in the hopper and turning the valve (giving 1 xp 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 your own.
