Cremation

See also: Columbarium and Shades of Mort'ton (minigame)

Cremation is the ability to burn bones on a bonfire or portable brazier for Prayer and Firemaking experience. It is a rare drop from ghosts and ghost-like monsters (see below). Upon receiving the ability, players will receive a game message: You have unlocked the ability to burn bones on bonfires!

Cremation was initially a reward from the 2014 Hallowe'en event, costing 10,000 points. After the event, it (and ghost hunter equipment) was added as a rare drop from ghostly creatures, much like the ectoplasmator before it.

Mechanics

Cremating bones grants 2.5× the burying experience for the bones in Prayer and 2× the burying experience in Firemaking. For example, dragon bones grant 72 Prayer experience when buried; cremating dragon bones grants 180 Prayer experience and 144 Firemaking experience.

While cremation grants less experience than using a gilded altar or the Ectofuntus, it is competitive with these methods due to the Firemaking experience granted and the speed of usage (particularly compared to the Ectofuntus). Additionally, ironmen can use cremation as an alternative to the gilded altar that does not require training Construction or purchasing the materials needed (if they are lucky enough to get it as a drop). Cremation is also the only of the three methods that free to play players have access to.

Bones cannot be cremated on permanent fires, only player-made bonfires and braziers. Cremation cannot be done inside Dungeoneering instances, using any kind of bones on fires in the instances will result in "Nothing interesting happens" message appearing.

Cremation does not stack with brawling gloves or bonus experience weekends. Only bones can be used for cremations; ashes do not work. The speed of burning a bone is 4 ticks (2.4 seconds), or 3 ticks with perfect clicking.
