Editing Codex - Emperor's Nightmare (section)

==Special Rules==

'''Sleep Beckons:''' Although the chapter's Dreadnoughts are supported by interfaces which prevent their chassis from becoming non-functional when the sleep takes them, these technologies are complex and a touch crude. At the beginning of the game, after deployment but before the first turn, roll a die for each non-Icelus dreadnought in your army. On the roll of a 1, sleep threatens to take the afflicted Dreadnought. From the second turn onwards, take a Leadership test for each afflicted Dreadnought, with a penalty equal to the turn number minus one; Dreadnoughts without a leadership score count as LD10 for the purposes of this roll. If this is failed. the Dreadnought falls asleep; its Weapon Skill and Ballistic Skill are each reduced by two, to a minimum of 1. If there is another non-afflicted Dreadnought or a Techmarine on the field, Weapon Skill and Ballistic Skill are each reduced by only one, by a minimum of 1.

'''Redundant Crew:''' Because of the danger that a vehicle's crew will fall asleep at any moment. The crew of Nightmare fighting vehicles include an extra member when possible. Each crew member is extensively cross-trained to allow them to take over in the event that another marine is incapacitated. 

If a vehicle is shaken or stunned at the start of your shooting phase, roll a dice. On a roll of 4+ all shaken effects are ignored and the vehicle may shoot normally. On a roll of 1 this ability is lost because one of the crew has fallen asleep. Crew Stunned results can be negated on a 6+. A roll less than six has no effect, even if the tank has extra armour.

'''Among Equals:''' The rarity and priceless nature of the chapter's terminator armour has forced the Nightmares to be flexible when deploying them. Because of this scarcity, Terminator combat squads are sized at 3 instead of 5. They often stand together or split apart at a moment's notice to fit the situation on the battlefield. Each and every terminator is a leader in his own right and will command or follow his brothers without hesitation.

Any number of models or squads wearing terminator armour may join together into a single unit, as though each model bore the independent character rule. Once attached to a squad these models may not leave it if the total number of models in the unit would drop below 3. 

You may join OR split models once at the beginning of the movement, shooting and assault phase. Any action you take must respect unit coherency rules at all times.
