Shattered Kingdoms

Ok, after messing with this all day, is it possible to get the weapon to fly ONLY on a critical hit, and add lag to the person who got disarmed like if they were bashed or tripped, but you know they were disarmed so they have to wait to reequip their weapon. Since we can't pick stuff up in a fight now and we can't carry 234131231231231231323 weapons, would lag for the person being disarmed work better and only give the weapon flying on a crit hit?
