Lakrimae

A model attacking with this weapon never receives +1 Attack for fighting with two Melee weapons (see page 177).

If a model is in base contact with more than one enemy model in the Initiative step in which they fight, they gain a number of Attacks equal to the value of X as noted in the variant of the special rule (if no value of X is included then count the value of X as 1).

If a model has this special rule, or is attacking with a Melee weapon that has this special rule, they always Wound on a 2+ in close combat.
Similarly, if a model makes a Shooting Attack with a weapon that has this special rule, they always Wound on a 2+.
In either case, this special rule has no effect against Vehicles or Buildings.
