Syreen’s Call is a special attack that can be used against a single enemy unit in the Shooting phase, even if the Syreen 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 Syreen is engaged in combat, her Syreen’s Call can only target an enemy unit in base contact.
To resolve a Syreen’s Call, the target unit must pass a LD test or suffer -3 to their LD until the start of the Syreen's next Shooting phase.
