Collapsing Singularity Before firing the weapon, roll a D6. On a result of a 1, the firing Knight-Atrapos suffers a single Hull Point of damage with no saves of any kind before the attack is carried out. On a result of a 6, the attack is carried out with the Vortex special rule.
Armourbane If a model has this special rule, or is attacking with a Melee weapon that has this special rule, it rolls an additional D6 for armour penetration in close combat.
If a model makes a shooting attack with a weapon that has this special rule, it rolls an additional D6 for armour penetration. In either case, this special rule has no effect against non-vehicle models.
