Hit Points
Hit Points (HP) determine how much health a character has remaining. All damage subtracts from this score, and if it reaches 0, the character can no longer participate in battle, and must be revived. HP can be restored via medicinal herbs, healing spells, resting at an inn, etc.

In Dragon Quest III and IV, Resilience directly determines your character's maximum Hit Points. The more a character's Resilience score increases upon leveling, the more Hit Points a character will receive upon the next level increase. In all other titles the maximum HP a character has is generally determined by their level and, if applicable, vocation. Martial artists, warriors, and paladins have the highest HP on average.
Any character can consume a seed of life to increase their maximum HP.
