Arcane Compendium

The Arcane Compendium serves as Ars Magica 2(AM2)'s guide book and needs to be obtained before any process in AM2 can being. Similar to the Thaumonomicon it has documentation of all the features that the mod currently contain. And likewise most of the documentation is normally hidden, requiring certain conditions (such as reaching a certain Magic Level) to be met before it is reveal.

Creation
To obtain an Compendium, a Item Frame containing a Book must be place above a pool of Liquid Essence. Spell runes will then float out of Essence and "infuse" the Book with arcane knowledge resulting in its transformation into an Arcane Compendium.
