Bones detail

Bones are the remains of the dead and can be used to train the Prayer skill. They are dropped by most monsters around Divine Reality with animal or humanoid appearance. Monsters that do not drop bones include demons and imps, spirits and ghosts, spiders and insectoids, among others. Some monsters drop specific type of bones, such as big bones, bat bones, monkey bones, or dragon bones. Normal bones give 4.5 Prayer experience when buried.
