The volcanic shard is an item dropped by Har-Aken and its TzekHaar variant, TzekHaar-Aken, that can be used to unlock the miniature-boss pet Shrimpy. The shard is awarded to the player and placed in their inventory upon Har-aken's death. A free inventory slot is required to obtain the shard. This requirement does not apply if it is obtained from TzekHaar-Aken, as it is directly sent to the Challenger's chest.
As with most boss pet items, the Volcanic shard follows the drop threshold system; it has a base drop rate of 1/200 and a threshold of 40.
