I read that to mean that if you’ve got the Killing Strike talent there is a scenario in which you can overrule the later wording about Wounds not blowing through to secondary targets within the mob/squad–it’s one of the perks associated with taking that talent.
I understand that in case of this Talent, there is an exception to the rule that Wounds are not applied to secondary targets.
If this were not the case, the rather expensive Killing Strike Talent would be totally useless versus mobs or squads. You need to cause a Wound in the first place, then you need to spend 2 Momentum to cause the additional wound. This is quite a restriction, so it is a justified exception for propagating wounds to mobs and squads, I think.
That makes sense but i wish the writers had been explicit in their rules. I ask because an upcoming game is featuring squads for the first time. Am expecting KS to be used to chop through the minions.
