A Space Marine Librarian (including Tigurius) may use the
psychic disciplines found in the Warhammer 40,000 rulebook,
instead of those in Codex: Space Marines. If he does so,
generate two new powers from the Biomancy, Pyromancy,
Telepathy or Telekinesis disciplines (in any combination) before
armies are deployed. Tigurius instead generates three new
powers.
Что в этом абзаце дает предпосылки считать, что эпистолярий знает 3 психосилы?
