Hello everyone !!!
Next White Dwarf has Rules for Sisters of Silence in Warhammer 40000 !
I know the rules are in french so here a small translation :
Chasseuse de Sorciers :
When resolving a melee attack against a psyker you can reroll the wound roll.
This unit can't be targeted or affected by psychic power. Also Psychic Test or Deny the Witch test suffer -1 for each units from your army with this power within 18" (max -4)
Dame du Néant :
If your warlord have Imperium keywords (unless fallen) you can include this unit in a vanguard detachment with QG restriction changed to 0-2 and bonus : None.
protocoles D'accusation :
Sniper against Psyker
Rest of rules are standard stuff
