Nature's Gift is an accessory which can be found randomly growing on grass deep within the Underground Jungle. It looks similar to a blue Jungle Rose, and does not glow nor light up when using a Spelunker Potion. When the flower is cut by any weapon or by other means, Nature's Gift will drop and can then be picked up by the player. While it is a decent accessory in its own right, Nature's Gift can also be used to craft the Mana Flower, which is a far more useful magic-enhancing accessory.
The Nature's Gift is the only equipable item that grows on grass, other than the Jungle Rose. That being said, it is the only non-vanity equipable item that grows on grass.
