Lunar spellbook

The Lunar spellbook contains only spells directed at skills and teleportation spells. There are a few spells that can affect combat, like Vengeance and Potion share, but they do not directly inflict damage.
Every Lunar spell requires some Astral runes, special runes that cannot be bought or created in the common ways.
You can change your current spellbook to the Lunar spellbook by talking to Meteora in Al-Kharid, Falador or Edgeville.

Be aware of the fact that if you cast a Support spell or a Group teleport from the Lunar spellbook, your target(s) must have Aid on in their settings. If a Group teleport is used, the target(s) have to accept this teleport first before they will be teleported.

To change your spellbook back to normal from another book, like the Ancient spellbook, or Lunar spellbook, you can speak to the Dark mage in the building in Edgeville, north of the bank, or in Draynor village.
