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

=====Ordo Hereticus Melee Weapons=====
*'''Null Rod''': It would be an average power sword if it weren't for its special Witchbane rule, which prevents the unit with this item from being targeted by all Psychic Powers, friendly or enemy.  In addition it also has the Instant Death rule if used against enemy Psykers, and at AP3 it can kill a surprising amount of opponents.  Hell, two Inquisitors with Null Rods and a Priest will have a guaranteed kill on a Hive Tyrant (mathhammer wise) so long as the Priest challenges, while remaining cheaper (although to that end a Culexus Assassin would have been better for the job).
:Feel free to laugh as [[Magnus the Red]] struggles to deal with puny humans (Malleus and Hereticus Inquisitors) who are not only immune to his Psychic shit, but can also beat him in melee thanks to the The Grimoire dropping him to I2, the Brain Mines paralyzing him, and their hammers keeping him at I1 so he stays paralyzed.  Oddly enough a group of Inquisitors with this gear are far and away the best defence against him, so long as they can catch him in melee they've got (mathhammer wise) a guaranteed kill while costing a fraction of the Primarch's points.
::Note that while it stops Psychic Powers from affecting the unit, it doesn't prevent the unit itself from using them, so feel free to attach it to a Psyker-heavy force so that you can lob powers while remaining safe from Psychic counter-attack, and with all of the Psychic bullshit flying around, a Null Rod can easily be worth the points.  
*'''Thunder Hammer:''' An interesting buy. For 5 points less than a Power Fist you get Concussive, which is a nice bonus.  It's more likely to come into effect with your Inquisitor because his S6 blows will only insta-kill other mere humans.  Malleus' Daemon Hammer is better and cheaper; feel free to rage.
