Setting Spears or Pikes Against Flying Creatures

If a unit in regular formation on the ground has set spears or other pole arms to meet the attack of a flying unit, and the airborne attack is against the front sides of the defending figures, the unit with set weapons can roll x 2 AD against the flyers—even if the flying unit makes a vertical envelopment or a pass-by attack. If the flyers drop to the ground to make a normal land attack, the AD bonus for the defending unit does not apply unless the attacking unit is charging.

Although the ground unit is not the target of a charge when it is being hit by a vertical envelopment or a pass-by attack, it still must make a successful morale check in order to set its weapons. Failure of this check has no effect other than to prevent the setting of weapons.
