You create a foehn, a mountain wind that carries with it a miasma of disease, to blow through the spell’s area. Subjects in the area when foehn is cast must save or suffer the sickened condition for 1 minute per caster level. The area does not remain dangerous after the spell is cast, and those affected remain sickened even if they leave the spell’s original area. A character may remove the sickened condition from a target by making a Heal check with a DC equal to the spell’s save DC. This takes one minute of uninterrupted treatment.
