The Old Twirly Whirlies [Active] An Iron Hills Ballista always counts as declaring a Heroic Shoot each Shoot Phase for free. When the Ballista hits a target, place a 25mm marker directly underneath the actual target, then draw a 1mm wide line from the centre of the Iron Hills Ballista to the centre of the marker. Any shooting attacks (friend or foe) that have a Strength of 6 or lower cannot be made if they cross the line, or if they target a model within 3" of the line. If a shooting attack that has a Strength of 7 or higher crosses the line or targets a model within 3" of the line, roll a D6. On a 5+ the shooting attack is immediately cancelled and does not hit its target - otherwise it will hit as normal. At the end of the turn, remove any markers placed by this special rule.
Area Effect [Active] After rolling To Hit against the actual target, if the actual target was a Battlefield Target then all other models within 2" of the actual target suffer a Strength 5 hit and, if they survive, will be knocked Prone.
