Banner of the Entombed

(Rule)
Description: If taken by a Character, the bearer gains Special Ambush (Open Terrain). If taken by a R&F model, the bearer’s unit gains Special Ambush (Open Terrain) 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 Special Ambush (Open Terrain) also count towards Entombed.
