Chipped black stone crystal detail.png

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 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.[1][2] The thresholds take the combined total of both solo and group kills.[3]

Mod Orion: "Futon has 245 kills: You have a 4x higher chance to receive the pet on solo mode. You have not yet reached the threshold on group mode. That's a 4/300 (1/75) drop chance in solo. You remain on a 1/1500 in group. … I was actually wrong. It's a 5/300 (1/60) chance on solo. Regular roll + threshold + threshold + threshold + threshold."

We're VERY happy that our systems allow us to re-use the previous elite dungeon code for new ones." In response to the question: "Oh one more thing - does this same system work for ed1 (and is it likely that it will be like this for ed3?)"
