Toxic Burst

A dull green line bursts from your pointing finger to a point you choose within range and then with a hiss blossoms into a toxic cloud. Each creature in a 50-foot-cube centered on that point must make a Dexterity saving throw. A target takes 8d6 poison damage on a failed save, or half as much damage on a successful one.

The fire spreads around corners. It ignites flammable objects in the area that aren't being worn or carried.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for each slot level above 5th.
