Life Fruit

The Life Fruit is a Hardmode type of plant that grows on Jungle Grass in the Underground Jungle. Once harvested and used, a Life Fruit permanently increases the player's health capacity by 5, turning one of the hearts in the player's health meter golden.

Life Fruit can only be used once a player has reached the 400 health cap from Life Crystals. On the, Life Fruit will only grow after one Mechanical Boss has been defeated, but increases the spawn rate of them as you defeat more Mechanical Bosses. On the, Life Fruit can be found prior to defeating a Mechanical Boss, just in much smaller numbers; defeating a mechanical boss increases the amount that can grow.

A total of 20 Life Fruit are required to reach the maximum of 500 health capacity, at which point all of a player's hearts will be golden.
