A model with this special rule has the Hatred special rule against Daemons of Slaanesh or models with the Mark of Slaanesh. Furthermore, when making Fear tests, a unit containing at least one model with this special rule suffers a -1 penalty to its Leadership if it is engaged in combat with a unit that contains at least one model with the Mark of Slaanesh or the Daemon of Slaanesh special rule.
A unit comprised entirely of models with the Battle Focus special rule can either shoot and then Run, or Run and then shoot, in the same Shooting phase. The unit must complete both actions before you move onto the next unit - otherwise the chance to make the second action is forfeit. A model cannot Run if it fired a Heavy weapon during the same Shooting phase unless it has the Relentless special rule. Similarly, a model that has Run cannot then fire a Heavy weapon in the same Shooting phase unless it has the Relentless special rule. Models that cannot Run gain no benefit from the Battle Focus special rule.
During deployment, players can declare that any unit that contains at least one model with this special rule is attempting to Outflank the enemy. This means they are making a wide sweeping move to get behind enemy lines or come at the foe from an unexpected direction. When an Outflanking unit arrives from Reserves, but not Ongoing Reserve, the controlling player rolls a D6: on a 1-2, the unit comes in from the table edge to the left of their controlling player's own table edge; on a 3-4, they come on from the right; on a 5-6, the player can choose left or right. Models move onto the table as described for other Reserves. If such a unit deploys inside a Dedicated Transport, they may Outflank along with their Transport.
A unit that contains at least one model with this special rule automatically passes Dangerous Terrain tests, and receives +1 to its Jink cover saves (other cover saves are unaffected).
A model with this special rule has a 4+ cover save unless it remained stationary in its previous Movement phase.
