New Class: Primaris Psyker Inquisitor
Certain Inquisitors used to serve the Imperium of Man as Primaris Psykers before they have reached their current ranks in the Inquisition. They are among the rare sanctioned few who can wield Psychic powers legally. Since Psykers could present a potential danger to entire worlds, the Inquisition relentlessly hunts them down, and those who are strong enough are recruited into Imperial service, fulfilling vital roles – like the Primaris Psykers. Their powers are drawn from the Warp as a weapon to smite the enemies of the Emperor, and Inquisitors with the Primaris Psyker background are experts in harnessing these boundless energies. In combat they rely on their psychic powers, preferring light armour and psychically attuned weapons.
A Primaris Psyker Inquisitor channels otherworldly energies, but they always risk damnation, deadly backlash from the Immaterium, not to mention the corrosive consequences of this sinister power on his own psyche. In game terms, Psyker Inquisitors gain penalties for using psychic powers, which may spawn Warp anomalies, so this character class requires a very different gameplay style compared to the Crusader of the Assassin Inquisitor.
There are three main specialist Inquisitors with Psyker background in the game, depending on the special wargear they use. Aetherwalkers employ an ancient, psychically reactive armour that phases its wearer between the Immaterium and Realspace, permitting to travel short distances in the blink of an eye. The Empyreanists gain their most important power from the product of a secret research project: even the existence of this ceremonial armour is denied outside the Caligari Conclave, as it uses long-forgotten xenotechnology to create a Warp anomaly that halts the flow of time for a short duration. The Scryers have a lightly armoured, psychic-attuned suit, the Warpbound Armour, which permits the Psyker Inquisitor to project its disembodied presence over the physical world, to gaze beyond the veil and take a look around without being detected.
