Legiones Astartes (Thousand Sons) Cult Arcana: All models with the Infantry or Cavalry Unit Type (but not those with the Artillery or Automated Artillery Sub-type) with this special rule gain the Psyker Sub-type (this does not grant any Disciplines, but does not otherwise remove any Discipline a model already has access to). In addition, all models with the Infantry or Cavalry Unit Type and and the Character Unit Sub-type that have this special rule must select one Minor Arcana option ( See the Prosperine Arcana special rule). Any model with the Infantry or or Cavalry Unit Types and both the independent Character and Legiones astartes (Thousand Sons) special rule that does not already have one or more Psychic Disciplines may be upgraded for +15 additional points to gain a single Psychic Discipline from the Core Psychic Discipline list (see the Horus Heresy Age of Darkness rulebook, page 322).
