Bonecrusher necklace

The bonecrusher necklace is a necklace that can be created by combining the bonecrusher and dragonbone necklace with a hydra tail (which can be reversed). It requires level 80 in Prayer to equip and shares the same +12 prayer bonus as the dragonbone necklace.

The necklace possesses the effects of both the bonecrusher and the dragonbone necklace, being able to automatically crush bones while restoring prayer, saving an inventory slot. As such, the necklace must be charged with ecto-tokens (25 charges per token) and must be equipped for 9 seconds to gain the prayer restoration effect. A small sound effect can be heard when the nine seconds have passed. This effect does not stack with the Catacombs of Kourend prayer restoration effect.

Note: You do not need to equip the necklace for the bonecrusher effect to work.

The amount of points restored are as follows:
 * Bones restore 1 prayer point.
 * Big bones restore 2 prayer points.
 * Baby dragon bones, Wyrm bones and Drake bones restore 3 prayer points.
 * Dragon, wyvern, and dagannoth bones restore 4 prayer points.
 * Superior dragon bones restore 5 prayer points.

Trivia

 * When dismantling the Bonecrusher necklace, all three of its component parts will be returned to the player. This is in contrast to its confirmation screens which currently states that only the Hydra tail and the Bonecrusher will be returned, without mention of the Dragonbone necklace.
