|Tooltip||Permanently increases maximum life by 20|
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, while also restoring 20 health. Life Crystals are consumed upon 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.
