Life Crystal

A Life Crystal is an item that drops when a Crystal Heart is broken with a Pickaxe. When used, it increases the player's maximum health by 20, adding a heart to the player's health bar. It also restores 20 health when used, but only as long the character max health is below 400. Life Crystals are consumed on use. Multiple Life Crystals can be used to increase a player's maximum health until it reaches a total of 400, after which Life Fruits can increase the maximum further, to 500.

Once the 400 health ceiling is reached, Crystal Hearts can no longer be used, and attempting to do so will not consume the item. They can then be sold or used to craft Heart Lanterns.

Trivia

 * In the alpha version, bosses dropped Life Crystals.
