Activating the Bisdi pet by talking to Seiryu in the Shadow Reef
The Inert black stone crystal can be obtained as a very rare drop from the Black Stone Dragon. It may be used to unlock the pet unique to the boss. To activate the crystal, the player must speak to Seiryu the Azure Serpent inside The Shadow Reef after defeating The Ambassador while having the crystal in inventory. Seiryu will transform the crystal into a humming black stone crystal, which can be inspected to unlock the pet, Bisdi.
As with most boss pet items, the Inert black stone crystal follows the drop threshold system; 1/300 with a threshold of 60 in a solo, 1/1000 with a threshold of 200 in a duo, or 1/1,500 with a threshold of 300 in a trio. The thresholds take the combined total of both solo and group kills.
The easiest way to transform the Inert black stone crystal into the Humming black stone crystal is by completing a run of the Shadow Reef in Story Mode.
