This spell generates a bank of fog, similar to a fog cloud, except that its vapors are yellowish green and poisonous. These vapors automatically kill any living creature with 3 or fewer HD (no save). A living creature with 4 to 6 HD is slain unless it succeeds on a Fortitude save (in which case it takes 1d4 points of Constitution damage each round while in the cloud).

A living creature with 6 or more HD takes 1d4 points of Constitution damage each round while in the cloud (a successful Fortitude save halves this damage). Holding ones breath doesn't help, but creatures immune to poison are unaffected by the spell.Po
