Infernal ashes

Infernal ashes were first mentioned in the February Behind the Scenes newspost. They are 100% drops from black demons, abyssal demons, tormented demons, nechryaels, and most boss demons. They will be able to be scattered for 62.5 prayer experience or taken to the Ectofuntus for extra experience. They are also the quickest way to train prayer in Free-to-play. It takes 25 Infernal Ashes to fill an Infernal Urn. A Full Infernal Urn grants 1875 experience when teleported.

Trivia

 * In the knowledge base, it is stated as being a Free-to-play item, despite none of the monsters that drop infernal ashes can be found in the free-to-play game.
