Health Points (or HP, also known as "Hit Points") represents the amount of health a player or enemy has. If a target's HP is 0, the target is defeated and is unable to continue the battle.
HP increases when a player levels up. For each level up, the player's character's maximum HP increases by 40. Adding attribute points to the Earth attribute increases the player's health by 30 points.
HP can be recovered in battle by effects of back items, using Healing Scrolls, or using skills that heal HP such as Refresh.
