Hit Point
HP, or Hit Points, are a character stat that shows how much "health" your character has. It can be restored through items like Potions and spells like Aura. When it reaches zero, your character dies and can only be revived through the use of Athenian Water(also known as Revive in the SNES/PS version) or a spell like Raise or Araise. Winning a battle with a dead character brings them back with 1 HP of health.
All enemies have HP as well. When their HP reaches zero, they die.
