Dance Of The Unicorn

You surround yourself with a purifying, swirling mist that
washes the air clean of smoke, dust, and poisons.
Nonmagical contaminants, including inhaled poisons, are
automatically negated within the cloud. Dance of the unicorn
also grants everyone within the mist a +4 bonus on saving
throws against magical or supernatural gas effects, such as
acid fog, cloud kill, and green dragon breath.
The cloud of mist leaves everything within its area damp.
