How to Make Fiends and Influence People

The cracks in the deep green leather binding of this ancient book reveal an unwavering orange glow. After studying this book for 1 hour each day over the course of a year and a day, you gain permanent influence over one randomly determined humanoid on your plane, even if it is immune to being _charmed_ . This otherwise functions as the _suggestion_ spell (no _saving throw_ ). The target uses the statistics of a _cambion_ , but maintains its prior physical appearance. A __wish_ spell, or the destruction of the book via __disintegrate_ or similar magic, frees the creature from this effect.
