A magic marker is a tool item in NetHack. It is one of the most useful writing items as it can be used to write magic scrolls or spellbooks. Of course, to do this, you must have a blank scroll or blank spellbook upon which to write. Magic markers can also be used to scribble a message on the floor (which is about as permanent as an engraving) at a cost of a charge per two letters (thus writing Elbereth costs 4 charges). Magic markers can be recharged only once. Archeologists, Monks, Priests, Tourists, and Wizards all have a chance of starting with a magic marker.
