The witch spills a vial of a volatile solution at a point within range, where it splashes outward in a 5-foot-radius Sphere. Each creature in that Sphere must succeed on a Dexterity saving throw or take 2d10 Acid damage, or half as much on a successful save. On a failed save, the failing creatures also take 1d10 Poison damage and they are afflicted with the Poisoned condition.
