Spells (35e)

Stinking cloud creates a bank of fog like that created by fog cloud, except that the vapors are nauseating. Living creatures in the cloud are nauseated (Fortitude negates), making them unable to attack, cast spells, concentrate on spells, and so on. The only action a nauseated character can take is a single move (or move-equivalent action) per turn. These effects last as long as the character is in the cloud and for 1d4+1 rounds after he or she leaves the cloud. (Roll separately for each nauseated character.) Those who succeed at their saves but remain in the cloud must continue to save each round.
