Blueheart grass is an ingredient found in the Yulan continent. It is extremely rare and is thus considered a priceless item that would rarely even be seen in the market. When the blades of grass are torn apart, they will leak out a dark green fluid which is very cool when drunk. A single patch of Blueheart grass is worth tens of thousands of gold coins. Blueheart grass grows in places with a high density of natural elemental essence, especially in the Mountain Range of Magical Beasts. This means that any place where Blueheart grass grows is no ordinary place, which adds to the difficulty of obtaining any.
Blueheart grass appears as a grass with deep green blades that emanate a faint blue light. It is cold to the touch, as cold as ice.
