Grotesque bones

Grotesque bones are obtained in The Nexus training area. They show up in the player's inventory after banishing The Grotesque. The player can obtain more than one set of bones.

Burying the bones yields experience based on the player's Prayer level. However, much like ancient bones, they cannot be used on an altar in a player-owned house, crushed for use with the Ectofuntus, nor cremated in a bonfire. Despite this, additional experience is provided with a clan avatar, and the First Age outfit.

Grotesque bones do not stack in the bank.
