Cremation

Cremation is an ability earned during the 2014 Halloween event for 10,000 reward points. After the event, it is dropped by ghosts and ghost-like monsters. It is available to free players and members.

It allows burning bones on a fire and gives 250% prayer experience per bone as well as 200% normal burying experience as firemaking experience.

Accursed ashes and Infernal ashes do not work with this ability.

Trivia

 * This ability does not work on permanent bonfires. It is not a glitch. Jagex intends for it to work only with player-made fires.
 * If trying to cremate bones with Prayer brawlers on you will receive the message, "You cannot burn bones on a bonfire while wearing those brawling gloves."
