4. Blades of Putrefaction

If manifested, select a visible friendly DEATH GUARD unit within 18" of the psyker. Until the start of your next Psychic phase, add 1 to all wound rolls made by that unit in the Fight phase. Furthermore, any wound rolls of 7+ made for that unit in the Fight phase with a melee plague weapon (i.e. a plaguesword or any weapon with the Plague Weapon ability) inflict a mortal wound on the target in addition to any other damage.
