I'm not sure I understand how this modifier works. Let's say for example I shoot an alien with 100 AP damage, and their AP damageModifier is 1.0, or 100%. Does that mean they TAKE 100% of the damage, meaning all 100 points, or they NEGATE 100% of the damage, meaning they take 0?
Or if I set all of an armor's damageModifiers to 0.0, anything with that armor would be invulnerable? If I set it to 1.2, in the previous example the target would take 120 AP damage?
