The Obcenes have a special ability(ferocity) which allows them to counter before they are forced to retreat conversely the Riverwatch Riders have a special ability(vigilant) which states that enemy units can not counter the Riverwatch. In an instance where the Riverwatch force an Obscene unit to retreat can the Obscene attack or is that ability overruled by the Vigilant special ability.
I have read a post on here where it was stated that the Vigilant ability took precedence over Ferocity. My friend is not satisfied with that answer because it came from a members post and not from an agent of FFG. I was hoping to receive an official answer from an FFG representative however I am curious how other players resolved this and I am looking forward to hearing from players. Also, if anyone had can point me to a rules page that would resolve this that would be greatly appreciated as well. thanks in advance for your comment s and help.
