This table can be used to compare and decide on how to train with the bones for the most desired cost versus experience gained. Notice how the cost in coins per XP point varies greatly depending on how the bones are used — but also remember that the different methods have different training speeds. Notes: * It is assumed that two incense, mahogany or marble burners are lit while using the Gilded altar. * The costs only include the cost of bones. The cost of clean marrentills used with the burners is not calculated.
