With Prayer being one of the most expensive skills to train in Old School RuneScape, utilizing tools and methods to earn as much passive experience as possible is essential to saving gp and unlocking powerful prayers quickly.

While there are many items that provide bonuses to Prayers, as well as flat-out unlocking certain Prayers, the Bone Crusher is an item that helps speed up the Prayer training.

How to Get Bone Crusher in OSRS

Originally seen during the days of RuneScape 2, the Bone Crusher is an item that is primarily used while completing PvM content.

One of the few items directly associated with the Prayer skill without solely providing Prayer bonus, the Bone Crusher has a unique ability to help you passively train Prayer.

What Does A Bone Crusher Do?

A Bone Crusher in your inventory will automatically crush bones from monsters you kill, granting you half of the experience you would from burying them normally.

Eventually, if you complete the Elite Tier Morytania Achievement Diary, you will be able to get 100% of the experience as if you were burying them.

For a Bone Crusher to be active, it must be charged with Ecto-Tokens, which can be obtained by offering Buckets of Slime and Bonemeal to the Ectofuntus and then talking to the Ghost Disciple.

For each Ectotoken that is used on it, the Bone Crusher will gain 25 charges.

Note: Be sure you have a Ghostspeak Amulet when talking to him.

Amidst an experience lamp worth 15k experience and many other rewards, you can claim a Bone Crusher from her free of charge.

Bone Crusher Upgrade

While the Bone Crusher alone is a fantastic item to have when completing any type of PvM content, it can be upgraded into a Bonecrusher Necklace by using it with a Dragonbone Necklace and a Hydra Tail.

The Bonecrusher Necklace combines the abilities of the Bone Crusher and the Dragonbone Necklace.

  • Bone Crusher: Crushes bones upon killing a creature and grants Prayer experience.
  • Dragonbone Necklace: Upon burying/ crushing a bone, restores a specified amount of Prayer Points while worn.

That is how to get a Bone Crusher in OSRS!
