Editing Warhammer 40,000/3rd Edition Tactics/Witch Hunters (section)

===HQ===
*'''Cannoness''' - A solid choice, but you need to gear her up pretty heavily to make her really shine. Don't even bother if you're not going to shell out on at least a book of Saint Lucius and cloak of Saint Aspira. A Rosarius, while a tiny bit on the pricey side, would also not go amiss. A Blessed weapon is great for insta-killing Eldar, Imperial Guard and other Toughness 3 junk, but against Marines (and other Toughness 4), the Blessed Weapon is <s>garbage and not worth it</s> great as even though you don't instant kill them you get to wound on 2's, ignore their armour and can take whatever they dish back with your 2+ invulnerable save. Better yet give her a jump pack and an Eviscerator/Inferno Pistol and send her tank hunting, it's not like anybody else in your army is getting that shit done.
*'''Palatine''' - Seriously, forget what I just said and field a stripped Cannoness before this. There is almost never a good reason to field her no matter how small the game is.
*'''Ordo Hereticus Inquisitor Lord''' - A versatile HQ choice that almost never stacks up to a good Cannoness. Best taken with a psychic hood against opponents fielding psykers, otherwise pass on him. Psychic powers are overpriced bullshit in an army that rarely lacks bullshit. If you want assassins just take him as an elite choice instead.
** Note that if you DO want him or an Elite Choice version, you may want to bring a Psychic Power. Diving Pronouncement can be kinda funny as can Scourging or Word of the Emperor, Purgatus gets a bad rap but can be hilarious if you combine it with a Celexus assassin, let's see any sorcerer try to use any of his powers at Leadership 3-4. On balance though, most of the Psychic Powers are overpriced, but if you want to bring an Assassin and thus have to bring an Inquisitor, they can be kinda lulzy. Scourging is great on low armor units relying on Invuls to save them.
*'''Priests''' - Not an HQ choice per se, but instead attach to your other units. Great for <s>taking away your sisters' rapid fire rule as well as for getting them killed in charges.</s> actually being a decent counter-charge option on your Sisters, re-rolling to hit rolls with S5?  Yes please, just bring along Retributors (or more excorcists) for the long-range dakka you'll need, and don't worry about the mandatory charge if you don't want to charge, if you attach him to anybody firing bolters then they can't charge anyway.  Also gives you access to a bunch of units you probably didn't want. 

The following are special characters:

*'''Inquisitor Lord Karamazov''' - The inquisition's fluffy old guy. You want an inquisitor retinue that counts as a single monstrous creature and goes around the battlefield spitting hatred and meltafire? this is your man. You want something more geared towards competitive play? I'm sure games workshop will be releasing another marine codex for you soon you fucking robot.
*'''Saint Celestine''' - Basically a much more expensive jump pack Cannoness with some special rules. Dubiously worth the points and eats faith on death. If you really must put her with a seraphim squad and go push somebody's shit in.
