A Ghostly Howl is a special attack that can be used against a single unit in the Shooting phase, even if the Banshee has marched, charged, or is engaged in close combat. This attack has a range of 8" and needs line of sight to its target. If the Banshee is engaged in combat, its Ghostly Howl may target a unit in base contact.
To resolve a Ghostly Howl, roll 2D6+2. For each point by which the result exceeds the target unit's LD, the target unit suffers 1 Wound which Ignores Armour Saves. Ghostly Howl is a non-physical Magical Attack and Wounds suffered from it are distributed as if from shooting.
