During combat, whenever there are 5 or more enemies within your vision you begin to feel stage fright. Because of a traumatic event in your past, when you have stage fright a rumbling presence begin to make itself known within you. Each round, you must make a Wisdom saving throw against yourself, starting at DC 10 with each consecutive round increasing the DC by 2. After a failed save, the presence makes itself known by releasing a noxious volatile substance originating from your posterior. You create a 10-foot-radius sphere of Stage Flatus centered on yourself. The cloud spreads around corners, and its area is heavily obscured. The cloud lingers in the air for a duration of 1d4 rounds. Each creature that is completely within the cloud at the start of its turn must make a Constitution saving throw (spell save DC) against poison. On a failed save, the creature spends its action that turn retching and reeling. Creatures that don't need to breathe or are immune to poison automatically succeed on this saving throw.
