Living Metal, Command Protocols My Will Be Done: In your Command phase, you can select one friendly <DYNASTY> CORE unit within 9" of this model. Until the start of your next Command phase, each time a model in that unit makes an attack, add 1 to that attack's hit roll. Each unit can only be selected for this ability once per phase. Phase Shifter: This model has a 4+ invulnerable save. Relentless March (Aura): While a friendly <DYNASTY> CORE unit is within 6" of this model, each time that unit is selected to make a Normal Move or Advance, until the end of the phase, add 1" to the Move characteristic of models in that unit. Spirit of Madness: Each time this model makes a melee attack against a unit, if this model’s Leadership characteristic is higher than the Leadership characteristic of that unit, you can re-roll the hit roll. |

Datasheet-related Stratagems
RESURRECTION PROTOCOLS1CP
Necrons – Epic Deed Stratagem
Necron rulers possess sophisticated self-repair systems that can reknit their corporeal forms after even the most grievous wounds.
Use this Stratagem in any phase, when a NECRONS INFANTRY NOBLE or NECRONS INFANTRY CRYPTEK model from your army is destroyed. You can choose to roll one D6 at the end of the phase instead of using any rules that are triggered when that model is destroyed (e.g. the Surrogate Hosts abilities). If you do, then on a 4+, set that model back up on the battlefield as close as possible to where they were destroyed and more than 1" away from any enemy models, with D3 wounds remaining. This Stratagem cannot be used to set the same model back up more than once per battle.
RAREFIED NOBILITY1CP
Necrons – Requisition Stratagem
In a show of arrogant superiority, the Necrons' leader has brought the cream of their noble allies to war at their side.
Use this Stratagem before the battle, when you are mustering your army, if your WARLORD has the NECRONS keyword. Select one NECRONS CHARACTER model (excluding C'TAN SHARD models) in your army and determine one Warlord Trait for that model (this must be a Warlord Trait they can have); that model is only regarded as your WARLORD for the purposes of that Warlord Trait. Each Warlord Trait in your army must be unique (if randomly generated, re-roll duplicate results), and you cannot use this Stratagem to give a model two Warlord Traits. You can only use this Stratagem once, unless you are playing a Strike Force battle (in which case you can use this Stratagem twice), or an Onslaught battle (in which case you can use this Stratagem three times).
This datasheet has HQ Battlefield Role. Full list of Necrons units sharing same Battlefield Role follows:

Staff of light (shooting) used in following datasheets:
ASSAULT
Assault weapons fire so rapidly or indiscriminately that they can be shot from the hip as warriors dash forwards into combat.If a unit includes any models equipped with Assault weapons, that unit is still eligible to shoot with in your Shooting phase even if it has Advanced this turn, but you can only resolve attacks using those Assault weapons when you select that unit to shoot with. If a model shoots an Assault weapon in the same turn in which its unit has Advanced, subtract 1 from hit rolls when resolving that weapon’s attacks.
- Can be shot even if firing model’s unit Advanced.
- Subtract 1 from hit rolls if the firing model’s unit Advanced.
Obsidax used in following datasheets:
Select Weapon
When a model makes a close combat attack, it must do so using a melee weapon (i.e. a weapon that has the ‘Melee’ type). The weapons a model is equipped with are described on its datasheet. If a model is not equipped with any melee weapons, or if it cannot make an attack with any of the melee weapons it is equipped with, then that model makes its attacks using a close combat weapon, which has the following profile:
|
If a model has more than one melee weapon, select which it will use before resolving any attacks. If a model has more than one melee weapon and can make several attacks, it can split them between these weapons however you wish – declare which attacks are being made with which weapons before any attacks are resolved. If the selected weapon has more than one profile that you must choose between, you must declare which profile is being used at the same time. Different attacks made with such a weapon can be made using different profiles if you wish.
If your unit is making attacks with more than one melee weapon against a unit, and those weapons have different characteristics profiles, then after you have resolved an attack with one of those weapons you must, if any other weapons with the same characteristics profile are also being used to make attacks against that unit, resolve those attacks before resolving any attacks against the target with a weapon that has a different characteristics profile. Note that all the attacks you have declared are always resolved against the target unit even if, when you come to resolve an individual attack, no models in the target unit remain in range (this can happen because of models being destroyed and removed from the battlefield as the result of resolving other attacks made by the attacking model’s unit first).
- Each close combat attack is made with a melee weapon.
- A model makes attacks using the close combat weapon profile if it has no other melee weapons.
- If a unit attacks with multiple weapons, all attacks made with weapons that have the same profile must be resolved before resolving attacks with the next.

Normal Move
When a unit makes a Normal Move, each model in that unit can move a distance in inches equal to or less than the Move (M) characteristic shown on its datasheet, but no model can be moved within Engagement Range of enemy models.- Normal Move: Models move up to M".
- Cannot move within Engagement Range of any enemy models.
Advance
When a unit makes an Advance, make an Advance roll for the unit by rolling one D6. Add the result in inches to the Move (M) characteristic of each model in that unit until the end of the current phase. Each model in that unit can then move a distance in inches equal to or less than this total, but no model can be moved within Engagement Range of enemy models. A unit cannot shoot or declare a charge in the same turn that it made an Advance.- Advance: Models move up to M+D6".
- Cannot move within Engagement Range of enemy models.
- Units that Advance cannot shoot or charge this turn.
Fall Back
When a unit Falls Back, each model in that unit can move a distance in inches equal to or less than the Move (M) characteristic shown on its datasheet, and when doing so you can move it within Engagement Range of enemy models, but it cannot end its move within Engagement Range of any enemy models – if it cannot do this then it cannot Fall Back. A unit cannot declare a charge in the same turn that it Fell Back. A unit cannot shoot or attempt to manifest a psychic power in the same turn that it Fell Back unless it is TITANIC.- Fall Back: Models move up to M".
- Units that Fall Back cannot charge this turn.
- Units that Fall Back cannot shoot or manifest psychic powers this turn unless they are TITANIC.
Light Cover
When an attack made with a ranged weapon wounds a model that is receiving the benefits of cover from this terrain feature, add 1 to the saving throw made against that attack (invulnerable saving throws are not affected).- +1 to saving throws against ranged weapons.
- Invulnerable saving throws unaffected.
Engagement Range
Engagement Range represents the zone of threat that models present to their enemies. While a model is within 1" horizontally and 5" vertically of an enemy model, those models are within Engagement Range of each other. While two enemy models are within Engagement Range of each other, those models’ units are also within Engagement Range of each other. Models cannot be set up within Engagement Range of enemy models.- Engagement Range: 1" horizontally + 5" vertically.
- Models cannot be set up within Engagement Range of enemy models.
Charging with a Unit
Once you have chosen an eligible unit to declare a charge with, you must select one or more enemy units within 12" of it as the targets of its charge. The target(s) of this charge do not need to be visible to the charging unit. You then make a charge roll for your unit by rolling 2D6. This is the maximum number of inches each model in the charging unit can now be moved if they can make the charge move. To make a charge move, the unit’s charge roll must be sufficient that it is able to end that move in unit coherency and within Engagement Range of every unit that was a target of its charge, without moving within Engagement Range of any enemy units that were not a target of its charge. If this is possible, then the charge is successful and the models in the unit make a charge move so as to fulfil the above conditions. If this is impossible, the charge fails and no models in the charging unit move this phase.- Declare targets of the charge (must be within 12").
- Charge roll = 2D6".
- If insufficient to move charging unit into Engagement Range of all targets, charge fails.
- If charge successful, models make their charge move.
- Cannot make a charge move within Engagement Range of any unit that was not the target of the charge.
Engagement Range
Engagement Range represents the zone of threat that models present to their enemies. While a model is within 1" horizontally and 5" vertically of an enemy model, those models are within Engagement Range of each other. While two enemy models are within Engagement Range of each other, those models’ units are also within Engagement Range of each other. Models cannot be set up within Engagement Range of enemy models.- Engagement Range: 1" horizontally + 5" vertically.
- Models cannot be set up within Engagement Range of enemy models.
Overwatch
Certain rules enable units to fire Overwatch at an enemy unit before it can charge. If an enemy unit declares a charge that targets one or more units from your army that have such a rule, each of those units can fire Overwatch before the charge roll is made. A unit cannot fire Overwatch if there are any enemy units within Engagement Range of it. Overwatch is resolved like a normal shooting attack (albeit one resolved in the Charge phase) and uses all the normal rules, except that an unmodified hit roll of 6 is always required for a successful hit roll, irrespective of the firing model’s Ballistic Skill or any hit roll modifiers. In addition, when a model fires Overwatch, it does so at the charging unit. Any rule that states the unit cannot be targeted unless it is the closest target (e.g. Look Out, Sir) does not apply when firing Overwatch.- Overwatch: Before charge roll made, all charge targets that can fire Overwatch can do so.
- Can never fire Overwatch while enemy units are in Engagement Range.
- When firing Overwatch, shoot with unit, but attacks only hit on unmodified 6s.
Defensible (Set to Defend/Hold Steady)
If every model in an INFANTRY unit is on or in an Area Terrain feature with this trait, then it can either Hold Steady or it can Set to Defend (see below) when an enemy unit declares a charge against it.If every model in an INFANTRY unit is within 3" of an Obstacle terrain feature with this trait, then it can either Hold Steady or it can Set to Defend (see below) when an enemy unit declares a charge against it if, were you to draw a straight line, 1mm in thickness, between the closest parts of the bases (or hulls) of the two closest models in the two units, that line would pass over or through that terrain feature.
A unit cannot Hold Steady or Set to Defend while it is within Engagement Range of any enemy units.
If a unit Holds Steady, any Overwatch attacks made by that unit this phase will score hits on rolls of 5+. If a unit Sets to Defend, it cannot fire Overwatch this phase, but you add 1 to hit rolls when resolving attacks made with melee weapons by models in that unit until the end of the next Fight phase.
- INFANTRY units can Hold Steady or Set to Defend (if no enemy within Engagement Range}.
- Hold Steady: Overwatch attacks hit on 5+.
- Set to Defend: Cannot fire Overwatch but add 1 to hit rolls in next Fight phase.
Hit Roll
When a model makes an attack, make one hit roll for that attack by rolling one D6. If the result of the hit roll is equal to or greater than the attacking model’s Ballistic Skill (BS) characteristic (if the attack is being made with a ranged weapon) or its Weapon Skill (WS) characteristic (if the attack is being made with a melee weapon), then that attack scores one hit against the target unit. If not, the attack fails and the attack sequence ends.If an attack is made with a weapon that has an ability that says it ‘automatically hits the target’, no hit roll is made – that attack simply scores one hit on the target unit. An unmodified hit roll of 6 always scores a hit, and an unmodified hit roll of 1 always fails. A hit roll can never be modified by more than -1 or +1. This means that if, after all the cumulative modifiers to a hit roll have been calculated, the total modifier would be -2 or worse, it is changed to be -1. Similarly, if, after all the cumulative modifiers to a hit roll have been calculated, the total modifier would be +2 or better, it is changed to be +1.
Wound Roll
Each time an attack scores a hit against a target unit, make a wound roll for that attack by rolling one D6 to see if that attack successfully wounds the target. The result required is determined by comparing the attacking weapon’s Strength (S) characteristic with the target’s Toughness (T) characteristic, as shown on the following table:
| ||||||||||||||
If the result of the wound roll is less than the required number, the attack fails and the attack sequence ends. An unmodified wound roll of 6 always successfully wounds the target, and an unmodified wound roll of 1 always fails. A wound roll can never be modified by more than -1 or +1. This means that if, after all the cumulative modifiers to a wound roll have been calculated, the total modifier would be -2 or worse, it is changed to be -1. Similarly, if, after all the cumulative modifiers to a wound roll have been calculated, the total modifier would be +2 or better, it is changed to be +1.
Terrain and Cover
Some pieces of terrain can provide certain bonuses to units in your army. Each bonus and how to acquire it is described in the Terrain Features section of the Core Rules. If a model has acquired such a bonus (to it's Save, Leadership or other characteristics), it is considered as receiving the benefit of cover. There are ways for some models to ignore such bonuses while making an attack, but it should be known what kind of benefit is ignored (see the Rare Rules for clarification).
Saving Throw
The player commanding the target unit then makes one saving throw by rolling one D6 and modifying the roll by the Armour Penetration (AP) characteristic of the weapon that the attack was made with. For example, if the weapon has an AP of -1, then 1 is subtracted from the saving throw roll. If the result is equal to, or greater than, the Save (Sv) characteristic of the model the attack was allocated to, then the saving throw is successful and the attack sequence ends. If the result is less than the model’s Save characteristic, then the saving throw fails and the model suffers damage. An unmodified roll of 1 always fails.
Engagement Range
Engagement Range represents the zone of threat that models present to their enemies. While a model is within 1" horizontally and 5" vertically of an enemy model, those models are within Engagement Range of each other. While two enemy models are within Engagement Range of each other, those models’ units are also within Engagement Range of each other. Models cannot be set up within Engagement Range of enemy models.- Engagement Range: 1" horizontally + 5" vertically.
- Models cannot be set up within Engagement Range of enemy models.
Charging with a Unit
Once you have chosen an eligible unit to declare a charge with, you must select one or more enemy units within 12" of it as the targets of its charge. The target(s) of this charge do not need to be visible to the charging unit. You then make a charge roll for your unit by rolling 2D6. This is the maximum number of inches each model in the charging unit can now be moved if they can make the charge move. To make a charge move, the unit’s charge roll must be sufficient that it is able to end that move in unit coherency and within Engagement Range of every unit that was a target of its charge, without moving within Engagement Range of any enemy units that were not a target of its charge. If this is possible, then the charge is successful and the models in the unit make a charge move so as to fulfil the above conditions. If this is impossible, the charge fails and no models in the charging unit move this phase.- Declare targets of the charge (must be within 12").
- Charge roll = 2D6".
- If insufficient to move charging unit into Engagement Range of all targets, charge fails.
- If charge successful, models make their charge move.
- Cannot make a charge move within Engagement Range of any unit that was not the target of the charge.
Performing a Heroic Intervention
When a unit performs a Heroic Intervention, you can move each model in that unit up to 3" – this is a Heroic Intervention move. Each model in the unit must finish its Heroic Intervention move closer to the closest enemy model. Remember that a unit must finish any type of move in unit coherency.- Heroic Intervention: Move up to 3".
- Must end closer to the closest enemy model.
Living Metal
The Necrons' semi-sentient metal skin lets them heal mid-battle.
At the start of your Command phase, each model in this unit regains 1 lost wound.Reanimation Protocols
Should a Necron be slain, its body becomes wreathed in an eerie glow. Crawling limbs reattach. Sundered torsos and smashed skulls reform amidst emerald sparks. Witchlights flare back to life within dead eye-lenses and the Necron rises again, shambling back into their battle line. Those Necrons too catastrophically damaged to reform vanish instead, teleported away to their tombs for repair.
Each time an enemy unit shoots or fights, after it makes its attacks, if any models in this unit were destroyed as a result of those attacks but this unit was not destroyed, this unit's reanimation protocols are enacted and those destroyed models begin to reassemble.Each time a unit's reanimation protocols are enacted, make Reanimation Protocol rolls for that unit by rolling a number of D6 equal to the combined Wounds characteristics of all the reassembling models. Each Reanimation Protocol roll of 5+ is put into a pool. A Reanimation Protocol roll can never be modified by more than -1 or +1.
If the number of dice in that pool is greater than or equal to the Wounds characteristic of any of the reassembling models, select one of those models to be Reanimated. A Reanimated model:
- Is added back to its unit with its full wounds remaining.
- Can only set up within Engagement Range of enemy units that are already within Engagement Range of the Reanimated model's unit.
- Cannot, if it is your Charge phase, be set up closer to any enemy units that are targets of a charge declared by its unit this phase.
- No longer counts as having been destroyed for the purposes of Morale tests this turn.
Example: In the Shooting phase, an enemy unit targets and makes its attacks against a 5-strong unit of Lychguard, destroying 3 models and leaving another with only one wound left. The Lychguard units reanimation protocols are enacted, and you now make Reanimation Protocol rolls for it. Each Lychguard has a Wounds characteristic of 2, so you would roll a total of six D6s. If you rolled 1, 3, 4, 5, 5 and 6, you would put three dice into a pool. This pool contains enough dice to Reanimate one of the destroyed models, and so it is set back up on the battlefield. After that model has been Reanimated, there is only one dice remaining in your pool. This is not enough to Reanimate another reassembling Lychguard model, as it is less than the models Wounds characteristic; this dice is therefore discarded.
Aura Abilities
Some abilities affect models or units in a given range – these are aura abilities. A model with an aura ability is always within range of its effect. The effects of multiple, identically named aura abilities are not cumulative (i.e. if a unit is within range of two models with the same aura ability, that aura ability only applies to the unit once).
Command Protocols
The Necron nobility make war in a codified and relentless fashion. Their command protocols crackle out across multi-dimensional spectra from carrier-wave projectors, compelling their semi-sentient soldiery into battle one overriding directive at a time.
If every unit from your army (excluding DYNASTIC AGENT, C’TAN SHARD and UNALIGNED units) is from the same dynasty, and you select a NOBLE model to be your WARLORD, this unit is eligible to benefit from this ability and the following rules apply.
After both sides have deployed, but before you have determined who will have the first turn, you must assign a different one of the command protocols below to each of the first five battle rounds, and note this down secretly on your army roster.
Example: Matts army is led by an Overlord (a NOBLE), and every model in it is from the same dynasty, therefore he must assign command protocols. He selects the following, writing them down on his army roster:
At the start of each battle round, if any NOBLE units from your army are on the battlefield, the command protocol that you assigned to that battle round becomes active for your army until the end of that battle round. Each command protocol is made up of two directives. When a command protocol becomes active for your army, reveal it to your opponent and select one of its directives. Until the assigned command protocol stops being active, while a unit that is eligible to benefit from this ability is within 6" of a friendly NECRONS CHARACTER model (excluding C’TAN SHARD models), that unit benefits from the selected directive.
If the battle lasts for more than five battle rounds, then until the end of the battle, whichever command protocol was active in the fifth battle round remains active. The available command protocols are show below.
After both sides have deployed, but before you have determined who will have the first turn, you must assign a different one of the command protocols below to each of the first five battle rounds, and note this down secretly on your army roster.
Example: Matts army is led by an Overlord (a NOBLE), and every model in it is from the same dynasty, therefore he must assign command protocols. He selects the following, writing them down on his army roster:
- Battle Round 1 = 2 (Sudden Storm)
- Battle Round 2 = 3 (Vengeful Stars)
- Battle Round 3 = 5 (Undying Legions)
- Battle Round 4 = 4 (Hungry Void)
- Battle Round 5+ = 1 (Eternal Guardian)
At the start of each battle round, if any NOBLE units from your army are on the battlefield, the command protocol that you assigned to that battle round becomes active for your army until the end of that battle round. Each command protocol is made up of two directives. When a command protocol becomes active for your army, reveal it to your opponent and select one of its directives. Until the assigned command protocol stops being active, while a unit that is eligible to benefit from this ability is within 6" of a friendly NECRONS CHARACTER model (excluding C’TAN SHARD models), that unit benefits from the selected directive.
If the battle lasts for more than five battle rounds, then until the end of the battle, whichever command protocol was active in the fifth battle round remains active. The available command protocols are show below.
1. Protocol of the Eternal Guardian Temporary dimensional shielding flickers into being around the Necrons as they stand tall upon the battlefield like graven statues.
|
2. Protocol of the Sudden Storm Arcing energies leap from one Necron unit to the next, lending speed to their limbs and causing their eye lenses to blaze.
|
3. Protocol of the Vengeful Stars Criss-cross fire leaps from the Necron ranks, forming a blazing corona of deadly energy from which there can be no escape.
|
4. Protocol of the Hungry Void The Necrons strike with data-augmented accuracy, their murderous attacks as inescapable as the killing cold of space.
|
5. Protocol of the Undying Legions At a hissing static signal, nanoscarabs are released in boiling black clouds that whirl about the legions and effect constant repairs.
|
6. Protocol of the Conquering Tyrant The legions employ the strategies of their masters in perfect synchronicity, laying down hails of mechanically coordinated fire.

The <DYNASTY> and CORE keywords are used in following Necrons datasheets:
Fast Attack
Saving Throw
The player commanding the target unit then makes one saving throw by rolling one D6 and modifying the roll by the Armour Penetration (AP) characteristic of the weapon that the attack was made with. For example, if the weapon has an AP of -1, then 1 is subtracted from the saving throw roll. If the result is equal to, or greater than, the Save (Sv) characteristic of the model the attack was allocated to, then the saving throw is successful and the attack sequence ends. If the result is less than the model’s Save characteristic, then the saving throw fails and the model suffers damage. An unmodified roll of 1 always fails.
Invulnerable Saves
Some models have an invulnerable save. Each time an attack is allocated to a model with an invulnerable save, you can choose to use either its normal Save (Sv) characteristic or its invulnerable save, but not both. If a model has more than one invulnerable save, it can only use one of them – choose which it will use. If you use a model’s invulnerable save, it is never modified by a weapon’s Armour Penetration value.- Invulnerable save: Saving throw that is never modified by attacking weapon’s AP.
- A model with an invulnerable save can use it instead of its normal Sv.
Normal Move
When a unit makes a Normal Move, each model in that unit can move a distance in inches equal to or less than the Move (M) characteristic shown on its datasheet, but no model can be moved within Engagement Range of enemy models.- Normal Move: Models move up to M".
- Cannot move within Engagement Range of any enemy models.
The Warlord
While mustering your army, you can nominate one model (except a model with the FORTIFICATION keyword) to be your Warlord. That model gains the WARLORD keyword. If this model is a CHARACTER, you can also assign a Warlord Trait to it. Note, that more than one model in your army can have a Warlord Trait (e.g. by using Stratagems), but they are only considered your Warlord for the purpose of that trait.
