1: The durability of Altair sphere is fixed and unaffected by player HP or Def.

2: While Vita and Quad Aegis does not provide immunity to status effects, the shields do not take damage from burn and poison. Damage is dealt directly to the player’s HP until the player reaches a minimum of 1 HP.
3: Prevents damage thus preventing stagger.
