Cake of guidance

The cake of guidance is a quest item used in the Recipe for Disaster quest that must be used on the Lumbridge Guide in the Lumbridge Castle banquet hall in order to free him. It is made in a cake tin from an enchanted egg, enchanted milk, and enchanted flour — the same ingredients used to make a regular cake, but each ingredient is enchanted with knowledge by the Wizard Traiborn, who lives on the first floor of the Wizards' Tower. The cake cannot be eaten.
