Priestess of Ghaunadaur
Like regular driders, priestesses of Ghaunadaur can use weapons, and have a kick attack that causes webbing. Unlike regular driders, their bite is corrosive rather than poisonous, and they have an acidic passive attack. This probably reflects their allegiance to the god of oozes.
Ghaunadaur, god of fallen stars, slime, outcasts, and the discarded, is a peripheral member of the drow pantheon. He is worshiped mainly by disaffected drow, especially those warped into punishment forms and exiled by Lolth. The most powerful droven followers of Ghaunadaur are often former priestesses of Lolth, warped into drider form after failing one of their goddess's many tests.
