Bonecrusher

The Bonecrusher is a reward from the Dungeoneering skill. It requires 21 Dungeoneering and 21 Prayer. It costs 34,000 tokens at the rewards trader and is for members only.

This means a Dungeoneering level of at least 62 is required for the tokens needed when using the regular way of Dungeoneering. You could also gain tokens by completing Sagas but then you'll still need a higher Dungeoneering level than 21 in order to do it effectively. It is, however, possible to acquire the necessary tokens by completing the saga Three's Company over and over again but this is incredibly slow.

When a player has a Bonecrusher present in his or her inventory, all bones dropped by monster kills, or obtained from hunting, will be automatically converted into Prayer experience. It should be noted that the Bonecrusher does not have any effect on ashes dropped from demonic beings.

There is no way to replace a lost Dungeoneering reward except to earn more tokens and purchase a new one. It is recommended that such items as the Bonecrusher be used only when a player can be certain his/her character will not die or unless the bonecrusher is not a risked item, or surplus Dungeoneering tokens are available.

Uses
The item needs only to be kept in the player's inventory for it to take effect and may be found useful if players have a tendency to leave bones on the ground and not bury them. When a monster is killed with a Bonecrusher in the player's inventory, Prayer experience is rewarded in a way similar to Slayer experience (with bones missing from the drops), with no animation or anything similar occurring.

This means that this item won't slow players down at all compared to leaving bones on the ground. The Bonecrusher has no effect on drops when it is left in the bank and will not work if LootShare or CoinShare is active.

If a monster drops more than one bone, such as bloodvelds or jogres often do, all dropped bones that are the same type as the ones the monster drops as remains will be converted to prayer experience; the rest will appear on the ground as usual, as a separate drop. Also, long or curved bones will not be buried by the bonecrusher, as these are a separate drop too.

Bones dropped as notes, like those dropped by Cyclopses in the Warriors' Guild when using multi-token mode, are not affected by the bonecrusher.

The bonecrusher can be used together with the twisted bird necklace, split dragontooth necklace, demon horn necklace, Corruption Aura, Salvation Aura or Harmony Aura to regain prayer points.
