Free Strikes - A free attack that can immediately be made out-of-activation against a model advancing out of an enemy's melee range or LOS. This attack gains a bonus to the attack roll and a boosted damage roll. The free striking model is always treated as being in the the advancing model's back arc during this attack. Note though, that free strikes do not benefit from back strike bonuses. The attack follows all normal rules of declaring attacks otherwise. If a player takes control of an enemy model with spells like Domination or abilities like Seduction, then the model does not take free strikes from either friendly or enemy models.
le terme advancing est important. il ne faut pas le confondre avec un "place". Pendant l'"advance", la fig engage et est engagée.
