Tyrannofex

Once per battle, when an attack is allocated to this model, you can change the Damage characteristic of that attack to 0.

While this model has 1-5 wounds remaining, each time this model makes an attack, subtract 1 from the Hit roll.

This ability always takes the form Deadly Demise X. Each time a model in this unit is destroyed, after the units embarked within it (if any) have made their emergency disembark moves, roll one D6. On a 6, that model suffers a deadly demise; 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").  Example:* An Impulsor with a unit of Intercessors embarked within it is destroyed by ranged attacks. First, any unresolved attacks made by the attacking unit are resolved. Then the Intercessors make an emergency disembark move. Then the roll is made for the Deadly Demise* ability, and on a 6, that ability is resolved. Finally, the Impulsor is removed from the battlefield.

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.
