Health Points

Health Points (HP) are the measure of vitality in Terraria: Otherworld. NPCs, monsters, and players all have Health Points. A newly spawned player will start with 50 Health Points, or 5 hearts.

Damage
Health Points may be decreased if the players touch a monster or a projectile fired by a monster.

Restoring Health
Health Points may recover naturally if the character has not been damaged in a while.
