Master of Poisons [Passive]

(Rule)
Description: At the start of the Move Phase, before the Declare Heroic Actions step, the Betrayer may spend a Will Point to use this special rule. If he does, then until the End Phase of the turn, friendly models with the Poisoned Attacks special rule within 6" of the Betrayer may re-roll all failed To Wound rolls for their Poisoned Attacks, rather than just To Wound rolls of a natural 1.
