Empyric Channelling At the start of the Psychic phase, you can nominate one Librarian from this Formation. If you do this, the nominated Librarian has access to any psychic powers known by other Librarians from this Formation within 12" until the end of the phase; however, other Librarians from this Formation within 12" of the nominated librarian cannot manifest psychic powers until the end of the phase.
Furthermore, when the nominated Librarian makes Psychic tests this phase, he will harness Warp Charge points on a result of 3+ rather than 4+ if there is one other Librarian from this Formation within 12", or 2+ rather than 4+ if there are two or more other Librarians from this Formation within 12"
