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.
Spore Burst If, when the final position of the first blast marker in the barrage is determined, there are
no models (friend or foe) under it, place D3 Spore Mine models anywhere under the blast
marker so that they are in unit coherency and not within impassable terrain or 1” of an
enemy model (any that cannot be placed are lost). These act as a Spore Mine Cluster for
the rest of the game.
