The Corpuscarii Electro-Priest advances as an arc-throwing skirmisher — Primary in Agility, Combat, Ferocity, Savagery and Shooting, Secondary in Brawn, Cunning and the Signature set. A frenzied flesh zealot, it grows quicker and sharper with its short-range arc, screening the wall as it burns the enemy at close range.
The Cybernetica Datasmith takes Primary from Brawn, Cunning, Ferocity, Leadership and the Signature set, with Combat, Savagery and Shooting as Secondary. Its advances bend toward command and the machine-rites by which it runs the robots, not toward fighting with its own hands.
The Fulgurite Electro-Priest advances as a melee striker — Primary in Agility, Brawn, Combat, Ferocity and Savagery, with only the Signature set as Secondary. As a frenzied flesh zealot rather than a construct, its growth is all speed, aggression and killing power: the fast blade the slow wall lacks.
The Kastelan Robot draws Primary from Brawn, Combat, Ferocity and Shooting, with no Secondary access. An autonomous war-robot run by its Datasmith, its advances only make it stronger, tougher and deadlier — the super-Brute grows more terrible, never more subtle.
The Kataphron Breacher advances as a heavy gun-platform — Primary in Brawn, Ferocity, Shooting and the Signature set, Secondary in Combat, Cunning and Savagery. Its growth deepens durability and firepower, the leaned construct body of the wall growing harder to shift and surer with its heavy gun.
The Kataphron Destroyer advances like the Breacher toward weight and firepower — Primary in Brawn, Ferocity, Shooting and the Signature set, with Cunning and Savagery as Secondary. A static heavy-gunner, its advances make it tougher and deadlier at range, never faster.
The Servitor barely advances at all — Primary access is Brawn alone, with Combat, Ferocity and Shooting as Secondary. A mindless construct, it learns little beyond holding its ground and firing; what growth it has hardens the cheap body the priests weld back together battle after battle.
The Tech-Priest Dominus draws Primary from Brawn, Combat, Cunning, Ferocity, Leadership, Savagery and the Mechanicus Signature set — the broadest access in the maniple, fitting the priest who leads it. Agility and Shooting come only as Secondary. It advances toward command and endurance, mastering the liturgy and the melee over speed or marksmanship.
The Tech-Priest Enginseer draws Primary from Brawn, Cunning, Leadership, Savagery and the Signature set, with Combat, Ferocity and Shooting as Secondary. It advances as a leader of the line and a master of the repair-rites — the priest that keeps the wall upright rather than the one that breaks it.
The Tech-Priest Manipulus shares the priests' access — Primary in Brawn, Cunning, Leadership, Savagery and the Signature set, Secondary in Combat, Ferocity and Shooting. Its advances favour the liturgy and the repair-rites, the specialist adept deepening its command of the machine over raw combat prowess.
