Thrashing Demise

While this Synaptic Imperative ability is active
for your army and a friendly HIVE TENDRIL
unit is within 6" of this SYNAPSE model:
• Each time you roll a dice for the Death Throes
ability of a model in that unit, add 3 to the roll.
• Each time a model is destroyed in that unit as a
result of a melee attack, if that model does not
have the Death Throes ability, roll one D6: on a
6, the attacking model’s unit suffers 1 mortal
wound after making all of its attacks.
