The Occult altar, also known as the Altar of the Occult, is built in the Achievement Gallery of a player-owned house as a place where players can switch their spellbook to one of the following: the Arceuus spellbook, Lunar spellbook, regular spellbook, or the Ancient Magicks. Other players can use the altar, provided they have the requirements to access those spellbooks.

In order to build the occult altar, players must right-click upgrade from the altar they have built, with the required materials dependent on the altar built. For example, upgrading the Ancient altar to the occult altar will require 1 lunar signet, 10,000 astral runes, 1 Arceuus signet, 5,000 blood runes, and 5,000 soul runes.

A saw is required in constructing the altar, and thus the crystal saw boost is applicable, making the minimum requirement level 82 Construction with a +5 boost from orange spicy stew.


These are the materials required to build an occult altar from scratch. Note if you're upgrading an altar, you will only need the items not used already.
