Toxicrene

At the end of the Fight phase, roll a D6 for each enemy model within 1" of any Toxicrenes. On a 6, that model's unit suffers a mortal wound.

If this model is reduced to 0 wounds, roll a dice before removing it from the battlefield; on a 6, it lashes out in its death throes, and each unit within 3" suffers 3 mortal wounds.

Unless a unit with this ability is within 24" of any friendly Synapse unit, you must subtract 1 from any hit rolls made for it when shooting any target other than the nearest visible enemy unit, and you must subtract 2 from its charge roll if it declares a charge against any unit other than the nearest enemy unit.

Each time this model loses a wound in the Fight phase, roll a D6; on a 6, the unit that inflicted the damage suffers a mortal wound after all of their attacks have been resolved.
