- Various (Restricted): Many other Psychic Disciplines exist throughout the galaxy, more secretive or forbidden that even the abhorred practices of the Imperium's sanctioned psykers. Some of these will be explored in future supplements, and likely require a corresponding Forbidden Knowledge Talent in order to learn.

Psychic Mastery represents a character’s abilities to call on the unnatural forces of the Warp to do their bidding. Through these techniques, they attempt to carefully focus a finite portion of the boundless power that exists within the immaterium to transform reality as per their desires. In the process, they endanger their very souls—and often the bodies and souls of everyone nearby. While an accomplished psyker might mitigate this risk, every use poses danger.
