Law rune

The law rune is required for teleport and telegrab spells, with a few minor runes depending on where you want to go.

For non-members, the main source of law runes will be NPCs that drop them, as most things that drop runes may occasionally drop law runes. For members, they may be purchased in the Mage arena, or made at runecrafting level 54 on Entrana, at the northeast of the island, after obtaining the talisman from the Troll Stronghold quest. Using the Abyss is another way to get there, and carrying the extra runes to enable teleport is highly recommended.

The price of law runes from other players tends to be high in free-to-play, since the the only source is occasional monster drops or visiting members. 1000 gp is expensive for a single rune, but it can save a lot of walking, or save your skin with a teleport out of trouble, though you cannot teleport at greater than level 20 wilderness
