Bones

Bones are used to train the Prayer skill, but they are not the most known bones in the game, as they give the lowest experience of them all. These bones can be dropped by all kinds of creatures, but mainly creatures with an animal or humanoid appearance drop them. If used on altar, the bones give x4.8 experience compared to burying. Regular bones give 5,000 experience when buried and 24,000 experience when used on an altar. It would take a player 544 bones if he or she would want to reach 99 Prayer starting by level one to level ninety-nine. All players drop bones when they die, including you.
