Life Fruit

The Life Fruit is a Hardmode plant found in the Underground Jungle which permanently increases the player's maximum health by 5, turning one of the player's life hearts golden. This goes beyond the 400 health cap of the Life Crystals, but to no more than 500 health, at which point every life heart is golden.

A total of 20 Life Fruits is needed to reach 500 maximum health. They can only be used once a player has reached the 400 health cap from Life Crystals.

Trivia

 * The plants on which the fruit grows have three different skins they can appear as, unlike the single type of skin that Life Crystals have.
 * The Life Fruit looks much like the Heart Container from the Legend of Zelda series, giving more health to Link, the protagonist of the series.
