Miasma

Starting at 5th level, if a blight druid is adjacent to a creature at the beginning of its turn, the creature must succeed at a Fortitude save with a DC of 10 + 1/2 the druid's level + the druid's Wisdom modifier or become sickened for 1 round. A creature of the animal, fey, or plant type that fails its save is nauseated for 1 round and sickened for 1 minute thereafter. If the creature makes its save, it is immune to this effect for 24 hours, as are creatures immune to disease.
