Repulsor

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.*
