SPECIAL RULES:
• The Aegis - A unit that contains at least one model with this special rule re-rolls results of 1 when making Deny the Witch tests.

• And They Shall Know No Fear - A unit that contains at least one model with this special rule automatically passes Fear and Regroup tests. When it Regroups, the unit does not make the 3" Regroup move, but can instead move, shoot (or Run) and declare charges normally in that turn. Furthermore, if a unit containing one or more models with this special rule is caught by a Sweeping Advance, they are not destroyed, but remain locked in combat instead.

• Brotherhood of Psykers (Mastery Level 1)

• Combat Squads

• Preferred Enemy (Daemons)

• Purity of Spirit - Grey Knights Psykers can only generate Sanctic powers from the Daemonology discipline, they cannot manifest Malefic psychic powers from this discipline. In addition, unless otherwise stated, when attempting to manifest psychic powers from the Daemonology discipline, Grey Knights Psykers only suffer Perils of the Warp if two or more 6s are rolled when taking a psychic test.

• Bulky
• Deep Strike
• Relentless - Relentless models can shoot with Heavy, Salvo or Ordnance weapons, counting as stationary, even if they moved in the previous Movement phase. They are also allowed to charge in the same turn they fire Heavy, Ordnance, Rapid Fire or Salvo weapons.

PSYKER:
Grey Knight Terminator Squads know the Banishment and Hammerhand powers from the Daemonology (Sanctic) discipline.

BANISHMENT: WARP CHARGE 1
Banishment is a malediction that targets a single unit with the Daemon special rule within 24". 
Whilst this power is in effect, all models in the target unit suffer a -1 penalty to their 
invulnerable save (normally reducing it to 6+). This is cumulative with any other modifiers to
a Daemon’s invulnerable save, but cannot make it worse than 6+.

HAMMERHAND: WARP CHARGE 1
Hammerhand is a blessing that targets the Psyker. Whilst the power is in effect, the Psyker
and his unit have +2 Strength.
