Universal Rule.
Shackled Slaves do not cause Panic Tests in other friendly units. At start of the First Game Turn and at the start of each friendly Player Turn, if the Shackled Slaves unit is not Fleeing, Shaken, or Engaged, choose a single friendly Standard Height unit with more than half of its models with Infernal Brand within 6″:
• If the Shackled Slaves unit is equipped with Shields, the chosen unit gains Soft Cover.
• If the Shackled Slaves unit is equipped with Paired Weapons, the chosen unit must reroll natural to hit rolls of ‘1’ with its Close Combat Attacks.
The effects last until the start of the next friendly Player Turn.
