Inausprechlichen Kulten

This tome takes the form of a great black book some two feet tall and nearly two feet wide. The text is a putrescent purple script that appears to be gibberish and is further confounded by the fact that the writing moves when not directly observed.

The great power of this text is that it can duplicate any spell placed next to it, making a perfect copy. The dark side of this is that seven days later the original text will catch fire in a terrible conflagration.
