Vitality Barrier

Vitality Barrier is an ability in Kingdom Hearts 358/2 Days that can be equiped via accessories or ability units for certain weapons. The ability itself decreases damage from single hits and combos down to ⅓ the usual damage while the player's HP is at full. You get this ability when you have the Recovery Ring on, or when you equip the Hazard Gear with two ability units (when playing as Roxas or Xion).
