Life Fruit

The Life Fruit permanently increases the player's maximum health by 5, turning one of the player's life hearts gold. This can go beyond the 400 health cap of the Life Crystals, but can be increased to no more than 500. They only spawn in the Underground Jungle, and can only be used once a player has reached the 400 health cap from Life Crystals. The Life Fruit, similar to Chlorophyte Ore, has a chance to regrow in the Underground Jungle, making it possible to farm an infinite amount of life fruit in the same world.

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.
 * They can be harvested with a sword, like other plants, instead of needing a pickaxe.
 * They glow when the player is under the effects of Spelunker Potion
 * They can't be used until the player has reached 400 health via Heart Crystals.
 * You'll need a total of 20 Life Fruits to reach the 500 max health.
 * Each world spawns with 20 Life Fruits upon reaching hardmode, thus there is little need to farm repeat worlds if you are looking for all 20 of them.
