Each Tech-Priest Auxilia unit must choose one of the following Techno-arcana. Only one selection may be made per Tech-Priest Auxilia unit. The Techno-arcana applies to the entire unit, providing it with additional special rules and wargear at no additional cost unless noted:
If a model with the Battlesmith (X) special rule is in base contact with, or Embarked upon, one or more damaged Vehicles, Dreadnoughts or Automata during the Shooting phase, they can attempt to repair one of them instead of firing a weapon. Roll a D6. If the result is equal to or more than the value listed in brackets as part of this rule then one of the following options may be applied to any one Vehicle, Dreadnought or Automata the model is in base contact with or Embarked upon: • Restore a lost Hull Point. • Restore a lost Wound. • Repair a Weapon Destroyed result. • Repair an Immobilised result. If a Weapon Destroyed result is repaired, that weapon can be fired in the following Shooting phase. The Battlesmith cannot use this ability if they are Pinned or Falling Back.
When a unit that contains at least one model with this special rule takes Morale checks or Pinning tests, the unit ignore any negative Leadership modifiers. If a unit is both Fearless and Stubborn, the unit uses the rules for Fearless instead.
Attacks with this special rule may re-roll failed Armour Penetration rolls against Vehicles and Buildings (both with Shooting Attacks and in close combat) and re-roll Glancing Hits, in an attempt to instead get a Penetrating Hit, but the second result must be kept.
Penetrating Hits caused by attacks made with weapons or models with this special rule add +1 to the result of any rolls on the Vehicle or Building Damage tables.
