Can Mephiston take 3 Psychic powers or 2 from the rule book? The rule book says 'A psyker's codex will usually state how many psychic powers the psyker has.' In this case three Sanguine Sword, Unleash the rage and Wings of Sanguinius. It goes on to say 'Where this is not the case the psyker has a number of psychic powers equal to his Mastery level.' In this case the GW FAQ states he is mastery level three. So at a glance, case closed he can take three... er no. The FAQ also says 'A blood angel librarian (including Mephiston) may use the psychic disciplines found in the Warhammer 40,000 rule book, instead of those in Codex: Blood angels. If he does so generate TWO new powers from blah blah...' So whats the crack in your opinions 2 or 3?
Many Thanks
