The Wall of Mirrors At the start of your shooting phase, this Formation can network their stealth fields to create a Wall of Mirrors. If you do so, then the weapons used by the Formation's Ghostkeels and by any unit of Stealth Battlesuits from this formation that are within 6" of a Ghostkeel from this Formation, have the Ignores Cover special rule, and these models add 1 to their BS for that Shooting phase. In addition, their weapons are assumed to strike the rear armour of any vehicle that they hit, no matter what its actual facing.
