Screamer-killer

Some models have 'Deadly Demise x' listed in their abilities. When such a model is destroyed, roll one D6 before removing it from play (if such a model is a TRANSPORT, roll before any embarked models disembark). On a 6, each unit within 6" of that model suffers a number of mortal wounds denoted by 'x' (if this is a random number, roll separately for each unit within 6").

If your Army Faction is **^^Tyranids^^**, while a **^^Tyranids^^** unit from your army is within 6" of one or more friendly **^^Synapse^^** models, that **^^Tyranids^^** unit is said to be within Synapse Range of that model and of your army. While a **^^Tyranids^^** unit from your army is within Synapse Range of your army:

■ Each time that unit takes a Battle-shock test, take that test on 3D6 instead of 2D6.
■ Each time a model in that unit makes a melee attack, add 1 to the Strength characteristic of that attack.
