Editing Warhammer 40,000/7th Edition Tactics/Grey Knights (section)

===Special Rules to remember===

*'''Brotherhood of Psykers:''' Now a USR, Brotherhood of Psykers basically just means that the entire squad counts as a single model when manifesting psychic powers, and you use the Sergeant's Ld for the test(or any model). Squads also get +1 to their Deny the witch rolls, due to the fact that squads count as being mastery level 1.

*'''Psychic Pilot:''' This universal special rule lets the vehicle use psychic powers as if it was a Mastery Level 1, Ld 10 psyker. Oh, and if it gets Perils of the Warp? Yeah, it rolls on the Perils of the Warp chart. The results in the Perils table are a bit of a mixed bag, but most of the results won't be catastrophic for them. Unfortunately, the only default Psy-pilots now are Dreadnoughts, but Storm Ravens can buy it back via the Death From the Skies supplement but it's at a hefty price.

*'''Combat Squads:''' Just like literally all other Chapters, Grey Knights like to split up into two five-man combat squads. Note that, thanks to Brotherhood of Psykers, splitting into combat squads will double the number of mindbullets you can put out each turn. 

*'''Preferred Enemy (Daemons):''' Makes sense that these guys have a rule meant for fucking over Daemons.  They get to re-roll 1s to-hit and to-wound.  This'll transfer even if they get attached to an allied commander.

*'''Aegis:''' The armour worn by Grey Knights has arcane seals and holy random stuff, meaning they don't give a damn about psychic powers. Whenever an enemy psychic power is activated,  a Grey Knight player may re-roll 1's when rolling to Deny the Witch. Not a huge bonus, but do you expect daemon hunters to go on a chaos safari without some protection against the Warp? That being said a lvl3 Lib with a staff will be denying on 3s against most witchfires and maledictions, re-rolling 1s and can bubble this 12" with his hood so your opponent gets blessings or nothing. 

*'''Purity of Spirit:''' This allows your Grey Knights to use Sanctic powers without suffering Perils on any double, instead just double 6's like any other power.
