Psychic Augmentation

While this Synaptic Imperative ability is active for your army and a friendly Hive Tendril unti is within 6" of this Synapse model:
Add 1 to Psychic tests taken for that unit.
Add 1 to Deny the Witch tests taken for that unit.
Each time a model in that unit would lose a wound as the result of a mortal wound,
roll one D6: on a 5+ that wound is not lost.
