Each time you gather attack dice for a **[BLAST]** weapon, add one additional **attack dice** for every five models that were in the target unit in the Select Targets step (rounding down). If this ability takes the form **[BLAST X]**, each time you gather **attack dice** for such a weapon, add **X** additional **attack dice** for every five models that were in the target unit in the Select Targets step (rounding down) instead. 
***Example:** If a **[BLAST 2]** weapon with an **A** characteristic of 3 targets a unit containing 12 models, you would gather four additional **attack dice** for that weapon (for a total of seven for that weapon).*

Each time an attack made with a **[DEVASTATING WOUNDS]** weapon results in a **critical wound**, the attack sequence for that attack ends and the target unit suffers a number of **mortal wounds** equal to the **D** characteristic of that weapon. These are inflicted after resolving any normal damage inflicted by those attacks. 
**Mortal wounds** inflicted by **[DEVASTATING WOUNDS]** weapons can damage a maximum of one model for each **critical wound**; any remaining **mortal wounds** inflicted by that attack are lost. 
***Example:** An attack made with a **[DEVASTATING WOUNDS]** weapon with a **D** characteristic of 3 results in a **critical wound** against an Intercessor Squad, so inflicts 3 **mortal wounds**. The first 2 **mortal wounds** are sufficient to **destroy** 1 Intercessor model, so the remaining **mortal wound** is lost.*

Each time a unit is **selected to shoot** or **selected to fight**, after that unit has resolved all of its attacks, make a number of **hazard rolls** (06.03) for that unit equal to the number of **[HAZARDOUS]** weapons you selected in the Select Weapons step.
