Burnt bones

Burnt bones are used to train the Prayer skill. When buried they give 4.5 Prayer experience. These bones, however, cannot be obtained as an item drop. They can only be found in the Demonic Ruins and Red Dragon Isle in the Wilderness. It is not possible to obtain these by using them on any source of heat such as a fire. They are no different to regular bones except that they have a burnt look, and that they weigh slightly less than regular bones. It is not recommended to train prayer with burnt bones, since they are only obtainable in the wilderness, and regular bones give the same amount of experience and are much easier to get.

Burnt bones were also used as a scam. People used to sell these bones for ridiculous prices, telling people they were rare. After the balanced trade update, this scam became impossible. With the reintroduction of free trade this scam is possible again, but not effective because of the guide price shown in the trade window.

Recently though, due to collectors and being hard to obtain, a lack of burnt bones in the Grand Exchange stock has caused a big increase in its price, from a few dozens of coins to coins. The best way to make profit with burnt bones is by running the distance from Daemonheim to the Demonic Ruins and going back, considering there are 9 burnt bones spawns in the Ruins and it is rare to be harmed by the demons, making the only danger in the activity PKers.
