Corpse Cloud

An object(s) you touch creates a 10-foot-radius sphere of nauseating gas centered on the object. The cloud can spread around corners. The cloud lingers in the air for the duration.

Each creature that passes through the cloud at any time during it's turn must make a Constitution saving throw (DC 13) against poison. On a failed save, the creature takes 1d12 poison damage and is poisoned for 10 minutes. Creatures that don't need to breathe or are immune to poison automatically succeed on this saving throw.

The subject of the spell can be burned to dispel the magical effects.
