Daemonic Assault
(Rule)Description: All units in the army always start the game in Reserve, even in missions that do not normally allow this rule to be used. you must declare if any Independent Characters are on their own, counting as a separate unit in reserve, or if they are joining a unit, in which case they and their unit are a single unit in Reserve. The enemy deploys as normal.
At the beginning of your first turn, divide the army into two groups that must include, as much as possible, the same number of units. Then nominate which of the two groups you wish to make a 'Daemonic Assault' at the beginning of the battle. Pick one of the two groups and roll a D6. On a 3-6 the chosen group will be deployed. On a 1-2 the other group will deploy instead.
The units in the group chosen for the Daemonic Assault arrive on your first turn using the Deep Strike rules. The remaining units are held in Reserve and their arrival is rolled for as normal. When a unit becomes available, it enters play by Deep Strike.
