Liber Magis Mortiferum

Summary
Liver Magic Mortiferum is a spell that is cast on a book, corrupting it and causing the inside to become a pocket dimension composed of a very long drop. The length of the drop is determined by the magical values of the book.

Magical Value is determined by the influence on magical history as well as the magical potential of the book. For example, a normal book would be weaker than a basic spellbook, which would be weaker than The Bible, which would be weaker than an advanced spellbook and so on.

If the victim of the spell hits the bottom of the pocket dimension and survived, they will be automatically teleported back out to their position before falling in, and the spell will be broken.

It is the stronger form of Liber Mors.

Uses
Liber Magis Mortiferum is used largely in the same way Liver Mors is used, as a sabotage method to kill rival mages from afar during wars. However, it is not used as much due to being harder to cast, especially on any more than one book at a time, as well as usually killing the target, which is often not the intent of spouts between mages.
