Chipped black stone crystal detail

A chipped black stone crystal can be obtained as a very rare drop from Seiryu the Azure Serpent. It is used to unlock the pet Kuroryu.

As with most boss pet items, the chipped black stone crystal follows the drop threshold system; it has a base drop rate of 1/300 in a solo instance, or 1/1500 in a group, with a threshold of 60 and 300, respectively. [1]
