Keethrax is a black druid living in the Druid Dungeon, and must be killed to satisfy the Kill Keethrax quest. Keethrax is hostile in a level filled with animals, including cats. These animals will be hostile even to PCs of the Druid class, presumably due to Keethrax' vile influence. Keethrax has a number of various attacks negating several combat strategies: A source of fire resistance (to reduce the damage from glowing balls) and a source of light (to negate darkness penalties) are highly recommended in the fight with Keethrax.
