Crystal acorn

A crystal acorn is used to grow a crystal tree in Prifddinas. After planting it, the crystal tree will grow instantly. One crystal tree blossom can be harvested from the tree per day, starting the day after it has been planted. Two blossoms will be received if the Tirannwn quiver 4 is equipped. It is not possible to boost your Farming skill to or past 94 to plant this seed, nor can it be assisted.
