Each time an enemy unit (excluding MONSTERS and VEHICLES) within Engagement Range of one or more RAVENWING units from your army Falls Back, all models in that enemy unit must take a Desperate Escape test. When doing so, if that enemy unit is Battle‑shocked, subtract 1 from each of those tests.
Each time a DEATHWING unit from your army declares a charge, if one or more targets of that charge are within Engagement Range of one or more RAVENWING units from your army, add 2 to the Charge roll.
