Editing Warhammer 40,000/7th Edition Tactics/Necrons (section)

===Decurion Detachment===
Remember how the Wardex explained that the entire operations of a Dynasty was essentially split into a whole ton of different little nodes that all connected to each other?
Yeah, the GW Design Team decided to run a formation made of formations as the new FOC of the Necrons and it's honestly kinda evil because there are ways to easily circumvent normal restrictions thanks to the limits of the Decurion.  It also doesn't help that doing this allows Living Metal vehicles to now ignore Crew Stunned and all members gain +1 to RP (meaning that Crypteks now feel kinda silly because now their job is pointless (Not Really. RP is 6+ vs ID. Back to 5+ in Decurion and 4+ again with a Cryptek. Sounds pretty shiny to me, especially when you're re-rolling 1's as below)).

*'''Reclamation Legion:''' Your mandatory force, this gives you an Overlord (anyone except for Imotekh), 0-2 Lychguard, 1-4 Immortals, 2-8 Warriors, 1-3 Tomb Blades, and 0-3 Monoliths.  Yeah, you need to use the silly little jetbikes.  However, getting this set up gives Move Through Cover, Relentless, and all members within 12" of the Overlord can re-roll 1s on their Rezzes. Unfortunately, the only thing Relentless actually gives any of these units is the ability to charge after firing Rapid Fire guns.
**'''Alternative Opinion''' - Tomb Blades aren't really silly anymore. With their cost going down (albeit only by 2) as well as unit capacity going up (from 5 to 10), and all of their upgrades costing no more than 2 points per model? Before 5 Tomb Blades with Shield Vanes and Nebuloscopes was 175 points. Now 5 Tomb Blades with the same gear is 110 points. They might not be competitive, but I wouldn't say they're laughable. Give them all particle beamers and watch horde armies cry because of 5 S6 blast weapons.  The salt can get very real.  Taking chunks out of MEQs is pretty fun.  Get about 15-20 hits on them; they may get their armor save, but those bolters don't do jack-diddly against T6, 3+ armor, and 4+ RP when they fire back.  Go nuts.
*'''Royal Court:''' Only allotted 1 per Reclamation Legion, this locks in an Overlord (who can be replaced with Imotekh), 1-3 Lords (one of whom could be Obyron), and 1-3 Crypteks (named or no).  If the Overlord is Warlord, he can re-roll his WT.
*The remaining forces are all locked to 1-10 per Reclamation Legion.  And some of them are just MEAN.
**'''Destroyer Cult:''' Destroyer Lord leads three squads of at least 3 Destroyers each and an optional squad of Heavy Destroyers.  The Destroyer Lord here can re-roll his WT if chosen and the Cult can re-roll to-wound and to-pen. This isn't too useful considering they all have Preferred Enemy anyway, but nothing to scoff at, especially when a Heavy Destroyer shoots at tanks.
**'''Judicator Battalion:''' Triarch Stalker joins 2 squads of Praetorians.  This grants the models Move Through Cover (though only the Stalker kinda needs it. Which is interesting, since the Stalker already has it by default. Wonder why they did that.) (It's so the praetorians don't have to take dangerous terrain when using jump packs and can ignore the difficult terrain penalty when charging), and the formation can now re-roll to-hit, to-wound and to-pen one unit the Stalker can see BUT only in your shooting phase (remember, praetorians have a range of 12" with their ranged weapons...). So, you will probably hate this formation because now, you MUST pay 2 squads of praetorians for EACH unit of triarch stalker you want to play in a Decurion Detachment. Ouch ! So, if you like praetorians, this formation is ok, but if you prefer to have a lot of triarch stalker unit (to give nearly all your unit a BS of 5 !) or simply don't want 2 squads of Praetorians, better include them in a Combined Arms Detachment. '''Note''': Due to FAQ Night Scythes taken as dedicated transports for the Praetorians, also benefit from the re-rolls.
**'''Canoptek Harvest:''' A Spyder joins a pack of Scarabs and Wraiths.  Sadly, you can't spam Scarabs until the cows come home without grabbing those other gits.  They all gain Move Through Cover and Relentless and during the Movement Phase, members within 12" of the Spyder can either pick RP, Fleet, or Shred.  All are neat, but shredding Scarabs is hilarious. Relentless Wraiths are also more than just hilarious, because now they get to fire their Transdimensional Beamers before charging. If you decide to keep the Wraiths cheap with Whip Coils, turn on Reanimation Protocols and laugh as anything that is not S10 or Destroyer harmlessly bounces off of 3++/4+ RP.
**'''Annihilation Nexus:''' Annihilation Barges join Doomsday Arks in blowing stuff up.  If the Doomsday Ark's Quantum Shields are out, then a Barge within 6" can shut their shields off to restore the Ark's shields.
**'''Star-God:''' You can field the Nightbringer, Deceiver, a Transcendent C'tan, or a Tesseract Vault - but usually you'll be better off grabbing a separate detachment of Conclave of the Burning One, of course.
**'''Flayed Ones:''' They're Flayed Ones.  Nothing else.
**'''Living Tomb:''' Obelisk comes with 0-2 more Monoliths.  The Obelisk always enters Turn 2, and Monoliths don't scatter within 12" of it.  Whenever a Monolith Deep Strikes, a unit of Infantry/Jump Infantry can jump from Reserves. Which is great because you '''''cannot''''' deepstrike and use the portal otherwise. Plus, Obelisks have smaller base sizes which means your monoliths are more likely to actually survive deepstrike.
**'''Deathmarks:''' They're Deathmarks.  What were you expecting?
**'''Deathbringer Flight:''' 2-4 Doom Scythes.  <s>Pretty much your chief source of AA.</s> Attack Flyers, so strictly for taking ground targets. Enemies within at least 12" of at least 2 of the Cronssants get -1 Ld and if one of them fires at something, the others gain +2 BS for each Scythe that fired on it. With DftS, can now do Attack Patterns, potentially getting BS 6 for the Leader, 7 for the rest of the wing, if they shoot the same weapon at the same target (effectively BS 10 with Tesla Destructors), on top of Ignore Cover and Tank Hunters. Bawkses will be crushed.

'''Important Note:''' Do keep in mind that you can run any of these formations alongside a normal Combined Arms Detachment. For example, if you want to free up some Elites, you can simply field a Judicator Battalion. Since Elites gain no bonus in a Combined Arms Detachment, you lose nothing, but gain three free Elites, a useful special rule and a reason to take your Praetorians out of the display case. The same trick can be used to gain some extra Heavy Support choices by using an Annihilation Nexus or a Deathbringer Flight.

'''Other Important Note:''' This detachment is good. Really, really, ''really'' good. It effectively makes your entire army 33% tougher than they would be otherwise, and overall ''twice'' as hard to kill as any other army would be with similar statlines. Your boys will be incredibly hard to shift no matter what you do with them; you will likely never be tabled, even against other tournament-grade armies. Unfortunately, combined with the general high quality of Necron units, it's ''too'' good, right up there with Riptide spam and Craftworld Cheese and Macaroni - many players will outright refuse to play against it. Score one for GW. Now you have all those models and nothing to do with them. Except not play Decurion and learn to take a loss or two.
