Rending If a model has the Rending special rule, or is attacking with a Melee weapon that has the Rending special rule, there is a chance that his close combat attacks will strike a critical blow. For each To Wound roll of a 6, the target automatically suffers a Wound, regardless of its Toughness. These Wounds are resolved at AP2.
Similarly, if a model makes a shooting attack with a weapon that has the Rending special rule, a To Wound roll of 6 Wounds automatically, regardless of Toughness, and is resolved at AP2.
In either case, against vehicles, each armour penetration roll of 6 allows a further D3 to be rolled, with the result added to the total. These hits are not resolved at AP2, but are instead resolved using the model/weapon's AP value.
Swarms If, when allocating Wounds to a unit with the Swarms special rule, two or more models could be chosen as the closest enemy, the closest enemy is always the model with the least number of Wounds. If a model with the Swarm special rule suffers an unsaved Wound from a Blast (any size) or Template weapon, each unsaved Wound is multiplied to two unsaved Wounds unless that Wound has the Instant Death special rule. However, a unit entirely composed of models with the Swarm special rule is not slowed by difficult terrain, but must test for Dangerous Terrain as normal.
Strength from Death Whenever a unit is completely destroyed within 7" of one or more non-vehicle units that consist only of models with this special rule, pick one of those units to make a Soulburst action. You cannot pick a unit that is locked in combat, Falling Back, or that has Gone to Ground. A unit making a Soulburst action can do one of the following, even if it has already done so in this turn:
* The unit can immediately move as if it were your Movement phase.
* The unit can immediately shoot (or Run or Turbo-boost) as if it were your Shooting Phase.
* The unit can immediately make a charge move as if it were your Charge sub-phase (if they do so, enemy units can fire Overwatch as if it were your Charge sub-phase). A unit that makes a charge in the Fight sub-phase does so at the end of the current Initiative step, and once they have charged, the Initiative steps continue to resolve as before (including for models in the charging unit).
A unit can only make a Soulburst action once per turn.
