The Acolyte advances as a generalist, its access kept deliberately broad. Cunning and Shooting are its Primary sets — the versatile bulk of the retinue trained to shoot straight and think fast — while Agility, Brawn, Combat, Ferocity, Savant and a taste of the Ordo Hereticus signature set all open as Secondary. It can grow toward almost any role the toolbox needs filled.
The condemnor-Crusader advances as a wall and an executioner. Its Primary access is the martial core — Brawn, Combat, Ferocity and Shooting — together with the Ordo Hereticus signature set that sharpens its anti-psyker shot. Leadership opens only as Secondary; the Crusader holds the line and takes the killing shot, it does not command it.
The Death-Cult Assassin advances as a pure killer. Its Primary access is Agility, Combat, Cunning and Ferocity — the speed and lethality that carry it to a cult-leader's throat — while only the Ordo Hereticus signature set opens as Secondary. It is a blade aimed at the marked heretic, and it advances to strike faster and surer.
The Inquisitor advances as the toolbox's mind and its faith. Its Primary access runs through Ferocity, Leadership, Savant and Shooting, and above all through the Ordo Hereticus signature set — the suppression and zeal skills that make it a witch-hunter rather than merely a commander. Agility, Combat and Cunning open as Secondary, rounding out a leader who directs the hunt more than he fights it.
The Interrogator is the broadest-skilled body in the retinue, the Inquisitor's hand trained to do a little of everything. Its Primary access spans Combat, Cunning, Ferocity, Leadership and Shooting, and carries the Ordo Hereticus signature set that lets it extend the master's suppression. Agility and Savant follow as Secondary. It advances toward whatever the hunt is short of.
The Pariah advances as a null-walker, tough and relentless. Its Primary access is Brawn, Combat and Ferocity — the resilience to carry its deadening presence into the enemy's casters — alongside the Ordo Hereticus signature set that deepens its anti-psyker work. Agility and Shooting open as Secondary. It grows toward walking further and enduring longer inside the warp's silence.
The Penitent advances, if it survives, as a berserk melee body. Its Primary access is Agility, Brawn, Combat and Ferocity — everything that drives a chained wretch into the enemy line and keeps it swinging — while only the Ordo Hereticus signature set opens as Secondary. It rarely lives to learn much; what it learns, it learns for the charge.
The Dialogus advances as the lone savant of the warband. Its Primary access is Cunning, Leadership and Savant — the skills of intel, litany and campaign craft that make it the retinue's mind between battles. Ferocity, Shooting and even the Ordo Hereticus set open only as Secondary; the scribe touches the hunt's doctrine lightly and leaves the suppression to the warders.
The Servitor barely advances at all. It has no Primary access; only Brawn, Savant and Shooting open as Secondary, and even those come slowly to a body that acts on command rather than initiative. A Servitor grows a little steadier at its single task, and no more.
