Big bones

Big bones are items associated with the skill prayer. Big bones give 15 experience points when buried. This is over three times as much experience as bones, making big bones an extremely popular method of training prayer in free-to-play.They are dropped by normally large monsters, such as Fire giants, Hill giants, Giant Frogs, Ice Giants, and Moss Giants.

Lately the price has been skyrocketing for big bones, most likely because of such high demand. Collecting them in the wilderness Bone Yard and selling them was one of the quickest non-merchanting ways to make money available for non-members. However, Clan Wars was built over the Bone Yard's location on December 10, 2007, reducing the only supply on big bones respawn for free players.

Big bones can be sold at the Grand Exchange for anywhere around 350-400 making it great way to make money. Similarly, bones have steadily increased in price on the GE: starting at 26 coins and currently at 94 coins. This is most likely due to the discrepancy in price and experience between bones and big bones, with big bones priced at 374 coins while yielding only 3 times the experience. However it is unlikely that bones will climb past 100 coins as the experience to cost ratio advantage would disappear.

Tips

 * For Members who have completed the Biohazard quest, there is an incredibly fast way to get big bones, made even faster if you have 51 magic. In the Training Ground North of Ardougne, many players train range quickly, so they leave the big bones from the ogres on the ground.  Enough Ogres are killed that there will be a massive supply of big bones.
