One of the most basic defensive formations any soldier knows, the shield wall has been used by many armies throughout the ages. When the entire front row of an armed group has a shield ready, they can move themselves in unison to deflect attacks not only aimed at themselves, but at their neighbors as well. The result is an overall improvement in both shield and armour effect in battle.

Using a shield wall is tricky. Those maintaining the wall must all remain together or the wall will break. This applies not just when one of the members flees the room, but also when a less skilled combatant is forced to 'step' away from the rest of his teammates. When this happens, that combatant must 'step' back into place, while his fellow party members must 'step' in the same direction, to keep the wall solid.

Discipline helps you maintain your formation. Leadership helps you form a better wall when you use the skill.
