Any unit that includes Aevos Jovan may not be targeted by a Shooting Attack by any unit or trigger any Reaction, unless at least one model in the attacking unit is within 12" of one or more models in the same unit as Aevos Jovan. However, if Aevos Jovan, or any model in the same unit, makes a Shooting Attack (including as part of a Reaction) then he loses this special rule for the remainder of the battle.
