You conjure a moving bank of poisonous fog. This functions as an Obscuring Mist spell except in the following ways. The area moves 10 feet away from you each round. It deals a number of d6s poison damage equal to half your Proficiency Score to each breathing creature that starts its turn in the spell’s area. Each creature must attempt a Fortitude save and takes only half damage on a success, full damage on a failure, and double damage on a critical failure. Cloudkill is on the Primal Spell List.
