Any psyker, including friendly psykers, withint 24" of the Culexus Assassin that attempts to use a power must roll a D6. If the roll is less than or equal to the number of force cards he played wit hthe psychic power, then the power is immediately nullified and the psyker suffers a wound with no armour saved allowed. If a power is played using the Ultimate Force warp card, the power counts as being powered by three force cards and cannot be nullified. However, the psyker must still roll a dice, if he rolls a 3 or less he takes a wound.
