"Unsanctioned Weaponry: Any model with this special rule in the detachment with access to a combibolter as an upgrade or option may instead take a xenos deathlock for +8 points or may exchange a combibolter they already possess for a xenos deathlock for +3

points."

Lethal Exposure: If a unit fires one or more weapons with this special rule in the Shooting phase, roll 2D6. If the roll result is less than the number of deathlock shots fired by the unit in that phase, the unit suffers a wound with no armour saves (Invulnerable and

Feel No Pain saves may be taken though) on a model selected by its owning player. Do not roll for Lethal Exposure in the case of

Overwatch fire.
