Tyrant Guard Brood

All enemy models in base contact with this creature reduce their number of Attacks by 1, to a minimum of 1.

Tyranids with rending claws inflict a wound automatically and ignore armour saves on to-hit rolls of 6. Other successful hits must roll ot wound as normal. If the creature rolls a 6 for Armour Penetration they then can roll an additional dice to determine the total Armour Penetration value.

The opposing player's line of fire is only blocked by terrain, vehicles and models in close combat while shooting at Tyranid models.
