Cloud of Spores (Druid Wild Shape)

Gaseous Form. The cloud of spores can enter and occupy the space of another creature. It can pass through small holes, narrow openings, and even mere cracks, though it treats liquids as though they were solid surfaces. It can't fall and remains hovering in the air even when stunned or otherwise incapacitated. It can't talk or manipulate objects, and any objects it was carrying or holding can't be dropped, used, or otherwise interacted with. A wind of moderate or greater speed (at least 10 miles per hour) drops the cloud of spores to 0 hit points. 

Toxic Cloud. The cloud of spores creates an area with a radius of 5 feet that contains toxic spores. It can designate any number of creatures that it can see to be unaffected by the toxic cloud. When an affected creature enters the area for the first time on a turn or starts its turn there, it must succeed on a DC 12 Constitution saving throw or take 6 (2d4 + 1) poison damage and have the poisoned condition. On a successful save, they take half as much damage. A creature that already has the poisoned condition and fails the saving throw has the paralyzed condition. A creature with either the poisoned or paralyzed condition may repeat the saving throw at the end of its turn, ending both effects on a success.
