Ir Abassin, Broodlost
From Destinypedia, the Destiny wiki
Ir Abassin and her shade acted and behaved like In Anânh, Brood Queen, where she casted Darkness Blasts, slammed the ground if anyone got too close, and occasionally used her Fire Nova Gaze. At half health, she split and summoned a shade, which also behaved like In Anânh's shade, where it used the Nova Scream and summoned a Brood Spike trap. However, unlike In Anânh, when the Shade was deposed, Ir Abassin was able to re-summon a shade, and once she was killed, the shade dissipated. Once killed, her death summoned a chest for the treasure hunt encounter.
