Bonecrusher

The Bonecrusher is a reward from the hard task set of the Morytania Diary. Players can obtain a Bonecrusher from the Ghost disciple in the Ectofuntus building. When carried in the inventory, it will automatically bury bones upon killing a monster. However, players only receive half the experience with the completion of the Hard tasks. In order to obtain full experience per bones, players must complete the elite tasks.

The bonecrusher can be recharged using ecto-tokens, giving 25 charges per token.The charge limit is 2,147,483,647. It is highly recommended that players do not store too many charges as all charges are lost if the item is destroyed. The bonecrushers uses 1 charge for every bone buried automatically upon kill.

The bonecrusher also does not auto-bury bones obtained as a secondary drop. This includes drops such as long and curved bones, as well as extra bone drops from mobs such as bloodvelds. Bones dropped as notes are not affected by the bonecrusher.

Obtaining charges
A good method to obtain constant charges is to perform the Ectofuntus daily by offering 26-39 bones after exchanging them into bonemeal and bucket of slime from Robin.

Usage
The item needs only to be present 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.

Catching hunter creatures which drop bones, such as those located in the Falconry will bury the bones while having the bonecrusher in your inventory.
