HP, an abbreviation for Hit Points or Health, is a stat in Dark Souls III.
General information
HP is a numerical stat that represents the survivability of the player. It depletes when damage is received and can be restored by healing. When it reaches zero, death occurs.
Increasing
The main way of increasing HP is through adding points to the Vigor stat when leveling up.
It can also be passively raised while wearing certain items, like the Life Ring. These items can be stacked to further increase HP.
By consuming an Ember the player will enter Lord of Cinder mode, which temporarily raises their total amount of HP to 140% of its base value until death occurs.
