Spellbook

A Spellbook is a list of spells available for casting to a player. There are currently three spellbooks: the standard spellbook, the Ancient Magicks spellbook, and the Lunar spellbook. A player may only cast spells from their current spellbook, and if they wish to use spells from another spellbook they must change to that spellbook.

It is possible to switch to and from Ancients to Lunar, without switching back at the former altar. For example, it is possible for players who are on Ancient Magicks to pray at the Astral Altar, where their spellbook will switch to Lunar. If players wish, they may pray again to deactivate the Lunar Spellbook and get their spellbooks switched to Modern.

Standard
The standard spellbook, also known as the modern magic spellbook, is available to all players and is the only spellbook with spells that can be cast at a low Magic level, while the other spellbooks can only be unlocked through members quests. This spellbook contains the most spells, as well as the most types of spells; offensive, defensive, alchemy, enchanting, teleportation.

Ancient Magicks
The Ancient Magicks spellbook becomes available to a player after that player completes the Desert Treasure quest. To change to the Ancient Magicks spellbook or back from the Ancient Magicks to the standard spellbook, a player must enter the pyramid in the desert south of Al-Kharid and west of Pollivineach from the rear and pray at the altar. The Ancient Magicks are composed of offensive and teleportation spells. Jagex updated the spellbook look on June 9th.

Lunar Spells
The Lunar spellbook becomes available to a player after completion of the Lunar Diplomacy quest. To change to the Lunar spellbook or back from the Lunar to the standard spellbook, a player must pray at the Astral Runecrafting altar on the southeast side of Lunar Isle. More Lunar Spells can be unlocked after completing Dream Mentor. The Lunar spellbook is the only spellbook that does not contain any offensive spells, it is instead composed of defensive, self-help, skill-related, and beneficial spells. There is a level 96 spell that allows you to change to another spellbook for one cast.
