Instinctive Behaviour - Hunt 1-3 - Burrow and Hide: The unit immediately Goes to Ground. Units that contain at
least one model with the Fearless special rule treat this result as Prowl (below), instead.
4-5 - Prowl: In the Shooting phase, the unit cannot Run and must instead shoot at the
closest enemy unit that is within range and line of sight of at least one model in the
Tyranid unit. If there is no viable target, the Tyranid unit can do nothing during the
Shooting phase. The unit cannot charge in the Assault phase.
6 - Destroy: This follows all the rules for Prowl (above). In addition, the unit gains the
Preferred Enemy special rule.
Smash All of the close combat attacks, except Hammer of Wrath attacks, of a model with this special rule are resolved at AP2 (unless it's attacking with an AP1 weapon). Additionally, when it makes its close combat attacks, it can choose instead to make a single Smash Attack. If it does so, roll To Hit as normal, but resolve the Attack at double the model's Strength (to a maximum of 10). Furthermore, a model making a Smash Attack can re-roll its armour penetration rolls, but must abide by the second result.
