Toxic Torrent

You exhale a torrent of virulent gas. Each creature in a 60-foot cone must make a Constitution saving throw. A creature takes 8d8 poison damage on a failed save, or half as much damage on a successful one.

A creature killed by this spell is wracked by seizures and chokes on its own bile, turning purple-black as it dies.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d8 for each slot level above 5th.
