The dragon chooses a point on the ground it can see within 120 feet of it. A 20-foot-radius, 20-foot-high cylinder of watery filth centered on that point erupts from the ground until initiative count 20 on the next round. Each creature in the cylinder when it appears or that ends its turn there must make a DC 15 Constitution saving throw, taking 10 (3d6) poison damage on a failed save, or half as much damage on a successful one. The cylinder is difficult terrain.
