Venomthrope Brood

The Venomthrope and any friendly units within 6" of the unit, can claim a 5+ cover save against any shooting attacks. In addition, these units count as being armed with defensive grenades and any non-vehicle enemy model that assaults one of these units must take a dangerous terrain test to represent the toxic effect of the spore cloud. Should the venomthrope be killed, these bonuses are immediately lost.

A Venomthrope's close combat attacks are Poisoned (2+)

see Instinctive Behaviour

A unit that Feeds is subject to Rage. In addition, the unit may not fire any weapons in the Shooting phase, though it may still run, according to the stipulations of Rage.

An enemy model that is in base contact with a Tyranid with one or more lash whips counts their Initiative value as 1 unit the end of the Assault phase, regardless of their actual Initiative.
