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

===Grand Convocation (Fall of Cadia)===
FINALLY. IT HIT. Now you have the means to field Knights, Skitarii and Cult Mechanicus units together in a single formation just as they always meant to be! In fact, you must field units from at least two different Factions in this FOC, and the restrictions strongly resemble a doubled Primary Detachment. You get '''2-4''' HQ units, which can be Belisarius Cawl himself, ordinary Tech-Priests Dominus (that's up to FOUR Domini!) or Enginseers, 4+ Troops, up to 6 Heavy Support, Elites and Fast Attack (all choices from both codexes are listed), and up to three Knights as Lords of War. Command Benefits include IWND for all vehicles (what did you expect? yes, your Knights repair themselves IN ADDITION to being tended to by Tech-Priests), PotMS for all vehicles within 6" of an HQ at the start of a turn, re-roll Warlord traits (any traits), and if you field a full FOC, [[Cheese|EVERYTHING gets Canticles of the Omnissiah]]* . Yes, you now have [[Awesome|self-aware undying stealth robots]]. This is the FOC to use, as it allows you to bypass both the Kataphron tax and the Dominus restriction, as well as giving you excellent anti-air (take a full unit of Dunecrawlers, upgrade one of them with the Icarus Array, and use PotMS with the other two walkers) and a monstrous [[DISTRACTION CARNIFEX]] that just won't go away, all without fiddling with other formations.

^^ But only If you play at apocalypse points levels "Canticles of the Omnissiah" is a bonus for fully filling out the FOC {except troops which has no limit} of this detachment even at minimum squad sizes with no upgrades it is simply not possible in 2500 points, in addition it stipulates what units you can take by name. So it removes the ability to take any forgeworld units in this detachment which is a major let down especially with the new imperial armour fires of cyraxus due out soon. Without the army wide Canticles of the Omnissiah the Conclave Acquisitorius which strangely does allow forgeworld knights or the war convocation are better for most games.

*Army-wide Canticles are just an icing, IWND and PotMS are already significant enough bonuses to take it. How Forgeworld handles their units is irrelevant, they should have adapted to the Decurion system long ago. You cannot take FW Knights in a Conclave since it specifically references Codex: Imperial Knights, so you will have to use a separate Detachment for these. And War Convocation is a WD exclusive, it might not be allowed everywhere and your opponents might refuse to go against it, while with Grand Convocation you can build a relatively normal AdMech army.

*This can also fill the holes in both Mechanicus Codexes. The Skitarii have great numbers of cheaper troops, but fewer tough units, (unless you count triple Onagers with IWND,) and their phosphor is rare and shorter ranged. (Unless you repurpose Dunecrawlers. The Cult Mechanicus have much tougher units. Kataphrons or Kastellans with Phosphor Blasters can play pseudo-markerlight for Rangers or Vanguard. Admittedly you'll still be hopelessly without transports, but you can still ally in a Land Raider. Heck you could possibly even fit some Infiltrator and Electro-Priests in the same vehicle! (You mad bastard!)
