Whirling your pointed finger through a complex gesture, you create a cool and fresh mist that cleanses the air of pollutants.

You surround yourself with a purifying, swirling mist htat 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, cloudkill, and green dragon breath.

The cloud of mist leaves everything within its area damp.
