Alarielle always strikes first in close combat. If an enemy also has this ability, the models strike in Initiative order (roll off in the case of equal Initiative values). If Alarielle hits her target, then no to wound roll is made. Instead the enemy model may make no attacks that turn, and any other models attacking it hit automatically that phase. In the case of a mounted model (on a chariot or monster, for example), Alarielle must roll to hit against the highest Weapon Skill, but if she hits then the entire model is affected, including any special attacks, impact hits, etc.
