Monofilament
(Rule)Description: When rolling To Wound for a weapon that has this special rule, use the target's Initiative instead of its Toughness (note that the model's Toughness is still used to determine whether an attack has the Instant Death special rule). In addition, if a 6 is rolled To Wound when attacking with a weapon that has this special rule, the Wound is resolved at AP2 unless the weapon is AP1.
