Health Points

Health Points (HP) are the measure of vitality the game employs. Both Monsters and players have Health Points. They may be damaged by Weapons or Explosives, drowning, touching Hellstone or Meteorite (without an Obsidian Skull), touching Lava, or by falling too far. Monsters are damaged for 999 Health Points if they are hit by Fallen Stars, though players will not be damaged by them.

A player's maximum Health Points can be increased by 20 by consuming one Crystal Heart item.

The Nurse NPC will only move into a suitable home once your maximum Health Points have been increased by 20.

The maximum possible Health Points is 400.
