A Law-rune is a rune that is required to cast teleportation spells and the telekinetic grab spell in the magic skill. Some teleportation spells such as ardougne teleport, will require two law runes per teleport. In addition to the law-rune(s), players will also need a specific combination of elemental runes depending on the spell. 8 Law-Runes are rewarded after completing Monk's Friend quest.
