Death Field
Weapons with the death field special property deal normal damage to shields, but they always deal minimum damage to Hull Points. Each time the weapon hits, a wave of negative energy floods the target starship. If the target has active shields on the quadrant hit, living creatures aboard the target take damage equal to the number of dice the death field weapon special property has. If the quadrant has no shields, roll the dice associated with the property once. Each living creature aboard the target vessel takes that amount of damage. This damage bypasses resistances and damage reduction. Undead aboard a targeted vessel instead heal an amount equal to the damage rolled.
