Lunar spells

Compare Ancient Magicks.

The Lunar Spells are a spellbook, like Ancient Magicks, that is accessible to players who have completed the Lunar Diplomacy quest. They make use of the latest rune, the Astral rune, and have several new teleportation spells as well as spells which aid in non-combat functions, reducing or eliminating the need for certain items and equipment to carry out certain tasks.

The Astral Altar
The spells are in a separate spellbook, and are swapped out with the normal set of spells by praying at the Astral altar southeast of the Moonclan city.

It is here that Astral Runes are also crafted via the Runecrafting skill. You cannot craft astral runes through The Abyss. One interesting feature of runecrafting Astral Runes is that if done with a friend or two, using the Tele Group Moonclan makes it more efficient in terms of spells and runes than simply running yourself and using the Moonclan Teleport, and the caster of the teleport uses no extra runes if an earth staff is wielded.

Trivia
If you pay close attention to the spells, you will notice that they are all passive spells. No real offensive spells are in the Lunar Spellbook.
