Dark Technomancers

When a unit with this obsession fires Overwatch or is chosen to shoot with, you can choose to enhance any or all of the ranged weapons models in that unit are equipped with. If you do, until the end of the phase, when resolving an attack made with that weapon, add 1 to the wound roll and add 1 to the Damage characteristic of that weapon for that attack. If any unmodified wound rolls of 1 are made for attacks with an enhanced weapon, the firing model suffers 1 mortal wound after shooting with that weapon.
