Description: • Ictus Insidiae: Any models with the Character Unit Sub-type in a Detachment that includes a model with this special rule may upgrade a machinator array or servo-arm they are equipped with to include an in-built prehensile data-spike for +10 points.
• Interfector Auxilia: Tech-Priest Auxilia units in a Detachment that includes a model with this special rule may choose the Interfector Techno-arcana instead of Enginseer, Lachrimallus, or Reductor options.
- Interfector: Tech-Priests and Magos Auxilia in the unit are each equipped with a prehensile data-spike. In addition, models in the unit gain the Scout special rule.
• Sacred Mission: A single Arcuitor Magisterium unit in a Detachment that includes a model with this special rule may be taken as an HQ choice. A unit taken in this way loses the Hunter Killer special rule and instead gains the Scout and Court of Executioners special rules. Note that this unit is still a 0-1 choice, so if it is taken as an HQ, another Arcuitor Magisterium unit cannot be taken as an Elites choice and vice versa.
- Court of Executioners: A unit with this special rule may include up to two additional Arcuitor Magisterium for 110 points each. When deployed onto the battlefield (either at the start of the battle or when arriving from Reserves), all models with this special rule in a unit must be deployed within unit coherency, but afterwards operate independently and are not treated as a unit.
• Scindex-malagrus: A model with this special rule gains the Preferred Enemy (Characters), Precision Strikes (5+) and the Monster Hunter special rules. In addition, a model with this special rule increases their Weapon Skill Characteristic to 5 and Attacks Characteristic to 3.
