Rend For each weapon with the Rend trait that a model has, that model rolls an additional D6 when making Fight rolls. Regardless of the number of Rend weapons a model has, it still cannot roll more than the maximum 6D6 when making a Fight roll.
Engine Killer (X) When a Vehicle, Super-heavy Vehicle, Knight or Titan suffers a Wound caused by a weapon with the Engine Killer (X) trait, they suffer a number of additional Wounds equal to the number shown in brackets. No Save rolls of any kind can be made against these additional Wounds. Note, only the model that suffered the first Wound suffers the additional Wounds; if this Wound causes to be destroyed, the additional Wounds cannot be assigned to another model within the Detachment.
If a weapon has the Engine Killer (X) trait and the Rend trait, enemy Vehicles, Super-heavy Vehicles, Knights and Titans suffer a number of additional Wounds equal to the number shown in brackets if they lose a Fight against the model that has that weapon.
Reach If Engaged with a Detachment, a model with a weapon with the Reach trait can choose to Fight other models within 2" of it that are not already paired off against another model, have not fought this round and are in the same Combat. The controlling player decides which model(s) it fights and can do this one at a time after resolving a Fight.
If both players have models with weapons with the Reach trait, the player with Initiative resolves any additional Fights first.
