The black stone dragon is the final boss in the Dragonkin Laboratory.

She was created by Kerapac, who implanted black stones onto a dragon from Vicendithas' old batch. The dragon also had a sister dragon; her whereabouts are unknown. The dialogue during the fight and the dragonkin research diary suggest that the black stone implants allowed Xau-Tak to influence her, which corrupted the dragon into her current form. After an accident which saw the destruction of another specimen, Kerapac sealed her away in the laboratory, for fear of her extremely uncontrollable nature.

DropsEdit

100% dropsEdit

The black stone dragon has two 100% rolls: one for the uniques (onyx dust, codex, pet, energy) and another for common drops (uncut gems and bolt tips). For clarity, the two tables are separated.
