The Corpuscarii Electro-Priest fields a spare, ritual kit. Its electrostatic gauntlets are its whole armament — gun and fist in one — and it may add an electrostatic field for a 5+ invulnerable save, light robes, and an augmetic limb. As a frenzied flesh zealot it takes no heavy guns and no repair-gear; it carries what it needs to close and burn, and nothing that would slow the charge.
The Cybernetica Datasmith arms for control, not the duel. It may carry an arc maul or servo-arm in melee, a phosphor or arc pistol as a sidearm, an auspex, and frag or krak grenades. Its control-uplink and servo-arm repair-kit are part of the chassis itself — the tools by which it commands and mends the Kastelan Robot — rather than separate purchases. Everything it takes serves the robots it directs.
The Fulgurite Electro-Priest carries only its electroleech stave and the barest augmetics — light robes, an augmetic limb or leg. A frenzied flesh zealot, it takes no ranged weapon and no armour heavier than its robes; its whole equipment is the stave that heals it as it kills and the will to reach the enemy with it.
The Kastelan Robot fields a fixed war-form: a heavy phosphor blaster on one arm and Kastelan power-fists on the other, ranged and melee both. Its protocol-core is part of the robot itself, switched each round by its Datasmith rather than bought separately. It takes no other gear — the war-robot is forged and consecrated whole, and fights with what it was built to carry.
The Kataphron Breacher mounts one heavy weapon — a torsion cannon or a heavy arc rifle — as its primary armament, with a hydraulic servo-arm for close work. It may take magna-stabilisers to brace and fire its heavy without the usual moving penalty. As a construct it carries no light guns and no field-kit; it is a gun-platform on tracks, built to plant itself and grind the wall forward.
The Kataphron Destroyer mounts the heaviest guns the wall fields — a plasma culverin or a heavy grav-cannon — and may take magna-stabilisers to fire them braced. It carries no melee weapon and no light kit: the Destroyer exists to sit in the line and level whatever the enemy sends, a static heavy-gunner the priests keep upright while it fires.
The Servitor is fitted with a single mounted weapon — an arc rifle or phosphor blaster — or a servo-arm for labour and close work, over light robes. A mindless construct lobotomised to one task, it chooses nothing for itself; the maniple fits it out and points it, and it carries only what it was built around.
The Tech-Priest Dominus commands the maniple's widest equip-list. In melee it may bear an Omnissian axe, servo-arm or arc maul; for a sidearm a macrostubber or radium pistol. It may add a refractor field, an auspex, mechadendrites and a cortex-controller that carries the Canticle further, and the full spread of grenades. As the Leader it arms to sustain the line and endure, not to win a duel.
The Tech-Priest Enginseer arms for repair first. It carries a servo-arm, Omnissian axe or transonic blade in melee and a macrostubber as a sidearm, and may add a refractor field, mechadendrites, and the galvanic regeneration-coils that deepen its Rites of Repair. Its servo-arm repair-kit is the chassis's own tool rather than a separate purchase. Frag and krak grenades round out a kit built to keep the wall standing.
The Tech-Priest Manipulus arms as adept and mender both. It bears a transonic blade or Omnissian axe with a macrostubber sidearm, and may add an auspex, a cortex-controller to extend the Canticle's reach, and the galvanic regeneration-coils that sharpen its Rites of Repair. Its servo-arm repair-kit is inherent to the chassis. Frag and krak grenades complete a versatile priest's loadout.
