Cloudkill

Range: Moves 6 ft per minute
Duration: 1 hour
Level: M5

Foul and poisonous vapors boil from the thin air, forming a cloud 15 ft in radius. The cloud moves directly forward at a rate of 6ft per minute unless its direction or speed is affected by winds. Unusually strong gusts can dissipate and destroy it. Poison-laden, the horrid mist is heavier than air, and thus sinks down any pits or stairs in its path. Even touching the cloud (much less breathing it) requires a saving throw to avoid immediate death.
