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

===Arcana Mechanicum===
*'''Autocaduceus of Arkhan Land''' - It's Arkhan Land's personal pimp cane. If he canes a hoe (or Kataphron, as the case may be) on the ass with it, they repair themselves. What this means is that it grants IWND to the bearer and his unit. It's also pretty expensive at 30 points. Can only be taken by the Techpriest Dominus
*'''Anzion's Pseudogenetor''' - [[Awesome|It's a tangle of mecha-tentacles that can vivisect enemies in the midst of battle]]. That's justification enough to use it. It's also pretty useful, as it allows a model using it to make D6 additional S4 AP5 melee attacks with Shred in addition to its normal melee profile. And it's only 15 points, too! If your Dominus even thinks about getting into combat, slap this on. Hilarity has a pretty good chance of ensuing if you get the Warlord Trait that gives all your close combat attacks Haywire.
*'''Raiment of the Technomartyrs''' - 2+ armor that grants the wearer's unit (so long as they're Cult Mech or Skitarii) Cognis weapons.  This makes allying with Skitarii absolutely lovely with cognis-plasma calivers. It's also prohibitively expensive at the price of a Plasma Caliver.
**Alternate Opinion: Nope. Nooope. You're paying a premium for a very useful special rule and a 2+ armour save together, when everything that can take this ''already has'' Artificer Armour. Pretty much the only thing that would make it worth using would be a huge unit of Breachers you want to put on anti-air duty, which can be done cheaper and better by a pair of Icarus Onagers.
***Another look: Or you could put this in a Cohort Cybernetica with Phosphor blasters and maybe a couple of incendine combustors, and have no one want to charge you ever. Invisibility or flying monstrous creatures getting you down? Well how does 24 str 6 ap 3 shots at BS 2 sound? Did I mention that half of them are twin linked? Expensive though, but worth it for the fact that it's in a super durable unit that can fire at different targets.
****One final look: If you are fielding Belisarius Cawl then you won't ever be choosing this over Memento-Mortispex. For the same points (30) the Mortispex offers the option of cognis, skyfire, tank hunter or monster hunter on a turn by turn basis. If only the Raiment offered an invulnerable save instead of its redundant armor save.
*'''Mask of the Alpha Dominus''' - Allows Kastelans or Cohort Cybernetica formation within 12" to automatically change their protocol and use it, but you lose access to the protocol you had before using it.
**Interesting fact: The rule description for the Mask says that you can use this effect ''at any time''. As in, your Kastelans just fired Overwatch twice, now you switch to the CC protocol and make the enemy eat 5 Power Fist attacks per model. Just, make sure not to break the Feel no Pain protocol, m'kay?
**Another thing to consider: If you give this to a Dominus, you can still change Protocols even if the enemy picked off your Datasmith, which you otherwise wouldn't be able to do. In other words, if you use a unit of Kastelans, ''strongly'' consider giving this to your Dominus.
*'''The Scryerskull Perspicatus''' - In addition to acting like a Scryerskull, it can be used on a vehicle to make all friendly units with the Cult Mechanicus or Skitarii faction reroll failed armor penetration rolls and the chance to reroll glancing hits scored against that vehicle for the duration of that turn. Another Arcana that can only be taken by the Dominus.
**Nowhere does it state that this relic replaces your normal Scryerskull. Meaning, you can either identify two Mysterious Objectives per turn (works especially well with the ''Archeotech Specialist'' Warlord trait) or identify one Mysterious Objective and scan a vehicle. Still, quite expensive for what it does.
*'''Uncreator Gauntlet''' - An odd relic that can be used in the Fight sub-phase in lieu of normal close combat attacks. To use it, nominate a vehicle the owner is in contact with (yours or the enemy's) and if the attack hits (or if you chose to use it on a friendly vehicle), roll a d6 and use the table below. If you're lucky, it can take a LR out in one strike or fully repair a vehicle that's about to be wrecked. Just hope you don't roll a 1. Invulnerable saves can be attempted against the HP loss, though each one has to be saved against individually. The fluff says this relic is used to rejuvenate machines back to the prime of their operative lifespan - ''maybe'' those cogheads should use it on the golden throne instead of striking shady deals with xenos, or maybe they'd end up with a great big hunk of parts and a manual by IKEA if they punched the Throne with it.
**1: Your opponent decides whether the vehicle is repaired for 1 HP or loses one HP. (All other results allow the user to decide whether it repairs or damages a vehicle).
**2-3: The vehicle is either repaired for 1 HP or loses 1 HP.
**4-5: The vehicle is either repaired for d3 HP or loses d3 HP.
**6: The vehicle is either repaired for d6 HP or loses d6 HP (!).
***Note that you can do this in addition to your Master of Machines rule. In other words, repair your vehicle in the shooting phase, then punch it with the Glove. Worst case, you roll a one, your opponent takes off the HP you just restored. Best case, your Knight that was down to 1HP is fully repaired now.
====Fall of Cadia====
The new book is giving us a new set of Arcana, some of which are pretty awesome! You can take items from it in any of the new formations or if you include Belisarius Cawl in your army.

*'''Numinasta's Casket of Electromancy''' — This is basically the Skull of Elder Nikola from the Skitarii list, but for Cult Mechanicus. 30 pts, can be used instead of firing a weapon, automatically hits everything including Flyers and FMCs in range. 2d6", S 3, AP -, Assault 1, Haywire, One Use Only.
*'''Quantum Annihilator''' — [[Awesome|AdMech Shokk Attack Gun]]. 30 pts, 18", S 2d6, AP 2, Assault D3. Roll for Strength after the target unit has been chosen, if you roll above 10, it [[Anal_Circumference|wounds/pens automatically with Instant Death]]. With the blessings of our Lord RNGesus, you can erase any pesky character or Monstrous Creature from existence with a single shot, or roll badly and simply wound some Terminators.
** It is worth noting that this will usually not be that good- an average roll on this makes it an 18" assault 2 plasma gun for 30pts.
** In most occasions in which you can access these relics, you can also field Skitarii. This can prove its worth as a good weapon for a Vanguard Alpha.
*'''Sacrifactum Autorepulsor''' — 15 pts, enemies charging the bearer suffer a -2" penalty on their charge move. With most HQs in this Codex, you WANT to be in close combat, though. Situational.
*'''Memento-Morispex''' — The big cheese. Remember all of the Grav, Plasma and Haywire in this army list? Now, for just 30 pts, you can apply Cognis, Skyfire, Tank Hunter or Monster Hunter to any unit by attaching a Dominus to them. Perfect for a large blob of Kataphrons armed with plasma- or grav-cannons, or a shooty Cohort Cybernetica maniple.
*'''Omnissiah's Grace''' — 10 pts for a 6+ Invuln or a +1 to an existing invuln to a max of 3+. Your Dominus can now have a storm shield for 15 pts.
*'''Saint Curia's Autopurger''' — The upgraded Pater Radium. 25 pts, enemy units get no bonus attacks for charging, and all models which are locked in combat with the bearer and their unit must pass a Toughness test at I10 step or suffer 1 saveable Wound for every failed test. Yes, this does stack with Skitarii Vanguards' Toughness penalty, and, if you're really cheap, Ordo Xenos Inquisitor's Rad Grenades. Your answer to being outnumbered by Orks and Tyranids.
