Drygha, Conjurer of Death is a Super Unique Death Maiden in Act V of Diablo III. She operates a Soul Crucible in the Gideon's Row during the Souls of the Dead quest, and only appears in Campaign Mode.
In combat, she is initially shielded from harm, and only becomes vulnerable when all four adjacent corpse piles are destroyed. She has Vortex, Fast and Teleporter traits, and attacks with multiple Reapers, which are summoned both by herself and by the crucible. Kiting her to the back of the row makes the fight easier by distancing it from the summon location of some of the Reapers.
After the fight, Drygha's Soul Crucible, larger than the one encountered earlier with Kasadya, must be destroyed manually. Myriam Jahzia then reveals that she had been hiding from the monster under several corposes.
