Psychic Cacophony
(Rule)Description: Does not affect Daemons
Roll a D6 if a psyker within 16" of one or more Noise Marines attempts to use a psychic power. Only 1 dice is rolled regardless of how many Noise Marines are within 16". Powers that remain in play will only be affected when first created. If the dice rolled is greater than the model's psychic level then it is overcome by the psychic cacophony and their power is nullified.
Wargear that offers protection against psychic attacks does not offer any protection against Noise Marines
A psyker who is overcome this way will suffer 1 Wound on a 4+ with no saving throw of any kind allowed.
