If taken by a Character, the bearer gains Underground Ambush. If taken by a R&F model, the bearer's unit gains Underground Ambush and additional models cannot be added to the unit during Army List creation. Standard Height models using this banner to Ambush must arrive in a formation containing exactly 5 models per rank (except for the last) and cannot make a Reform (or a Swift Reform) during this Player Turn. Units with Underground Ambush also count towards Entombed.
