The Primaris Psyker knows any Psychic Powers known by units of Wyrdvane Psykers from the same Division while they are within 12". In addition, add 1 to the Primaris Psyker's Mastery Level until the end of the Psychic phase for every 5 Wyrdvane Psykers from the same Division that are within 12" at the start of the phase. Note that this does not cause him to generate any additional powers.
