Editing Warhammer 40,000/Tactics/Imperial Agents (section)

====HQ====

*'''Ordo Malleus Inquisitor:''' Easily the most melee focused of the three, the Malleus Inquisitor still has access to the Daemonhammer, and he still has access to his Daemonblade, though they can now dual-wield them and the blades make it clear which of their effects affect the user, and which affect the blade (meaning that he can get four effects by using two blades, even though he can only attack in close combat with one), though you shouldn't expect something amazing out of it, even if you do purchase two swords for him.  His ranged weapons aren't that bad either, though getting a Psycannon costs a lot of points, as does the Terminator armour it requires (to the point that it's arguably not worth it), and the Hellrifle is almost cheap enough to spam it as a MEQ-killer (get some Astropaths for Prescience and this certainly becomes an option), though as already mentioned this Inquisitor mostly shines in melee.  Make him a Psyker, give him the Daemonhammer and Empyrean Brain Mines and let him go to town with his force weapon.
:If you want to make the most out of him and you happen to be fighting Daemons (or really anyone with the Daemon rule), then feel free to take the Grimoire of True Names, and use this alongside your Brain Mines to drop Greater Daemons down to I1, then smash them with the Daemonhammer.  It's not unheard of for Bloodthirsters to charge into fights against these guys and fucking lose.
:*'''Inquisitor Coteaz:''' Coteaz covers a lot of bases, and covers them very well.  He's a good psyker, has a decent enough ranged attack, is good enough in melee and doesn't cost a lot of points, what's not to love?  Well for starters even though his model is wearing a rosarius whoever wrote the rules didn't recognize it, so he has no Invuln save.  This is easily remedied by putting him in with a unit of Acolytes, with at least one of whom has a storm shield (though unfortunately he's kind of boned if he gets into melee combat with anyone S6 or higher).  Secondly his special rule, Lord of Formosa isn't really all that useful in the current rules, thanks to the fact that Daemonhosts and Jokaero are single-model units now (you can give three models ObSec, yay) and between the three, Daemonhosts, Jokaero and Acolytes make up all of the models he can give the rule to.
::That being said, he's still good for his points, and his I've Been Expecting You rule is nothing to sneeze at, in a properly shooty squad (gained by using the Inquisition's formation or by allying him in with another army) he can cause an absurd amount of damage in a very short time, and even if he doesn't, the bubble he generates that scares away Deep-strikes and Outflanks could easily be worth the price, though if you want an Inquisitor who isn't a jack-of-all-trades you'd be better off with the generic one. 

::'''Edit:'''  As Corteaz can be taken in the new Castelleans of the Imperium Detatchment in fall of Cadia, the Lord of Formosa rule will give all non-vehicle units in the detatchment Obsec, which is something the detatchment was missing, it is worth considering!
*'''Ordo Hereticus Inquisitor:''' The saddest of the bunch, though not fully without advantages.  Unfortunately the Malleus and Xenos both have more going for them than the Hereticus Inquisitors, and of the three the Hereticus is far and away the most specialized.  They also get shafted in odd ways, such as their thunder hammers costing 5 point more than the Malleus' version, and that one's a force hammer!  [[wat|Their power fists also cost 5 points more than their thunder hammers!]]  That being said, there are a number of ways to get a lot of use out of these Inquisitors, mostly through buffing/defending the unit they're currently in.
:Both of these revolve around using the Null Rod and Psyocculum.  The Psyocculum is straightforward, put him in a unit (even a unit of conscripts) and so long as you're shooting at a unit with psykers, they'll be BS 10.  Preferably you'll be using weapons meant more for killing the unit around the psyker than the psyker themself, as that means you get more out of it.  The Null Rod on the other hand is mainly meant for countering the psychic bullshit that's been going around as of late, simply put it makes the Inquisitor a miniature Culexus Assassin.  Their attacks are at AP3 with Instant Death against psykers (which encompasses a surprising amount of characters, hell two Inquisitors with Null Rods and an allied Priest can kill a Hive Tyrant while remaining cheaper) and no psychic powers may be used against them or their unit.  Getting a few Inquisitors with Null Rods to protect from Magnus and Ahriman could have been worth it on their own, [[awesome|even if this detachment didn't also let them come with their own Warlord Traits.]]  They can also take the Liber Heresius to further buff their unit, and considering the buffs it can offer it's well worth the 15 points to do so.
:*'''Inquisitor Karamazov:''' Still no Invuln save, still no Eternal Warrior, still gets ID'd by a railgun shot.  Put him in a unit that has storm shields to give him some sort of protection, or better yet add him to the Inquisition's formation, try to get the 12" range bonus from the Jokaero and laugh as he burns shit with a 36" multi-melta before crushing opponents in assault.
::Karamazov best shines in an assault-heavy army, preferably one that has alternate means of traversing the board (such as Marines with their Geomancy) but he can still work with the Inquisition, all you need is an Acolyte unit who got far in a transport (one of whom is a mystic), an Inquisitor who happened to get Gate of Infinity, and then you can deep strike Karamazov and his unit right next to the Acolytes without fear of scatter.  This is of course assuming you opponent's not coming to you, if they are then they'll have their work cut out for them as Karamazov can rip and tear with the best of them.
::Karamazov's also pretty good as a buffer too, Dread Reputation makes sure that he and everyone else around him stay exactly where they should be (functioning as a priest-lite, but for multiple units) while By Any Means Necessary is actually helped by the Daemonhost's new size of one model per unit, so long as you can get any of them into combat you can sacrifice a 10 point model to make sure his blasts don't scatter, which is more than worth it.  
:*'''Inquisitor Katarinya Greyfax (Imperial Triumvirate):''' 150 points costing a shitload more than a regular Inquisitor (also halfway between Coteaz and Karamazov), and debatably worth it. She has the exact same statline as normal inquisitors, but has a Master-Crafted Condemnor Boltgun, a Master-Crafted Powersword, and a Psyocculum in addition to her Psyk-out grenades.  While this doesn't excuse her cost, she's a ML2 psyker who always counts as having a higher level than the enemy to help deny, and one who can only take Telepathy, though she does also always know a unique power called Aura of Oppression: WC1 or WC3. The 1 Warp Charge version is a malediction targeting a single enemy non-vehicle unit within 12" which forces a pinning test, which even if they pass they cannot run, turbo-boost, sweeping advance, or fire Overwatch. The WC3 variant is instead a "nova Malediction" targeting all non-vehicle enemy units within 12". How much you plan on using her Aura is what's going to determine whether or not she's worth the hefty price tag.  It's great in particular at shutting down Tau Support fire bullshit and Dark Angels Supreme Fire Discipline (and it combos beautifully with Assassins and assault heavy Henchmen Warbands).  If you don't plan on using it, then don't get her, stick to a regular Inquisitor who can grab better more useful gear and abilities while costing less, and if you are going to use it then grab some Psykers (preferably Astropaths from the Telepathica) for extra charges.
*'''Ordo Xenos Inquisitor:''' A good shooter and de-buffer, of the three the Xenos Inquisitor is best suited for an all-comers list as their Rad Grenades, Plasma Syphon and Psychotroke Grenades all work wonders on everything.  Put them in an assault squad to help it mulch through the opponents and keep it safe from rapid-fire plasma, or give him a Conversion Beamer, sit him back, and start shooting.  Interestingly it could be argued that the rad grenades stack with each other, and since they don't stop at lowering their victims to T1, you could have three Inquisitors charge the same T3 target, and it would die before striking back at all.  While not ideal, this could also be used to cancel the new Pink Horror's bullshit split rule.
:Unfortunately the Ordo Xenos don't have a special character of their own since Inquisitor Valeria's now dead, presumably killed by Greyfax above.
