Accelerated Entropy

If manifested, select one enemy model within 12"
and visible to this Psyker. Both players then roll
one D6 and add their model's Toughness characteristic. If your result is higher than your opponent's, that enemy model's unit suffers
3 mortal wounds. If your result is double your opponent's, or more than double your
opponent's, that enemy model's unit suffers
D3+3 mortal wounds instead.
