Bones

Bones are the remains of the dead and can be used to train the Prayer skill. They are dropped by most monsters around RuneScape 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 types of bones, such as big bones, bat bones, monkey bones or dragon bones. Normal bones give 4.5 Prayer experience when buried. Starting at level one and only burying normal bones it will take 2,896,541 bones for skill mastery (level 99 at 13,034,434.5 xp). Players may also use the spell Bones to Bananas or the spell Bones to Peaches to turn normal bones to edible bananas or peaches. Bones can also be offered at the altar in a player-owned house.
