We allow our Libraians to purchase a power much like the "Seal Wounds" power from Dark Heresy. How it works is that once per 24hrs, the Librarian can heal a Battle-Brother at the Fettered, Unfettered and Push power levels (once at each power level). The character being healed in this way receives the number of hit points equal to the psy rating of the Librarian at the above levels. This power does not heal any critical damage taken. If the Battle-Brother feels that an upcoming encounter / combat requires additional healing, the Librarian can manifest the power again - however, unless the Battle-Brother being healed makes a Hard (-20) TOU roll, the psychic healing instead inflicts the number of hit points equal to the psy rating. This type of healing has the same chance of triggering psychic phenomena as using any other psychic power.

Rather than mix Chapters, our group looked at all the existing advanced classes, and then either: modified an existing one to fit our current Chapters, or built entirely new specialities that fit in with our Chapter histories / idealogies etc. We've tried to make as balanced as possible (with the other advanced classes), and all those that GM also reviewed them, to ensure no 1 Chapter has advantage over the others.
