Grey Knights Dreadnought [Legends]

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 **^^Grey Knights^^**, at the end of your opponent’s Fight phase, you can select a number of units from your army that are on the battlefield (excluding units that are within Engagement Range of one or more enemy units), providing every model in those units has this ability. The maximum number of units you can select depends on the battle size, as follows:

Incursion - Up to 2 units
Strike Force - Up to 3 units
Onslaught - Up to 4 units

Once you have made your selections, remove those units from the battlefield and place them into Strategic Reserves.
