Checking your Status
HP can only be recovered by returning to the castle or town of your Dynasty (by entering into a recovery area) unlike the Chi Shield which can be recovered by special potions and/or powders 'Vitality' indicates both HP and Chi Shield status. Though Chi Shield becomes zero, it does not affect your character, but if HP becomes zero, your character will die, and you will have to pay a penalty in most cases.
HP and Chi Shield and Vitality gauges
Character dies once the HP becomes zero.
Chi Shield, one of special characteristics of Chundo Online, is literally a shield that protects your character. It is consumed/lessen by enemy attacks before the HP. Chi Shield can be immediately recovered by special potion during a battle or by special powder when in a non combat state. However, only a little amount of Chi Shield can be recovered in a combat state. If Chi Shield becomes zero, HP will begin to decrease. If HP becomes zero, the character will die.

Monsters also have HP and/or Chi Shield.
However, unlike your character which has both HP and Chi Shield, some monsters have either HP or Chi Shield or both.
The blue gauge indicates Chi, a form of supernatural energy, which is required in activation of special skills of each character. Whenever you use a special skill, you consume your Chi and, if Chi becomes zero, you cannot use any more skill. A small amount of Chi can be recovered while in a combat state. Chi can be immediately recovered by a Chi recovery potion during a combat or by a Chi recovery powder while in a non combat state.
