You exhale a cone of magical gas in a 30-foot cone. Choose one of the following options: 

Sleep Breath. Each creature in the area must succeed on a Constitution saving throw or fall unconscious for one minute. This effect ends for a creature if the creature takes damage or someone uses an action to wake it.

Repulsion Breath. Each creature in the area must succeed on a Strength saving throw or be pushed 60 feet away from you. 

Slowing Breath. Each creature in the area must succeed on a Constitution saving throw. On a failed save, the creature can't use reactions, its speed is halved, and it can't make more than one attack on its turn. In addition, the creature can use either an action or a bonus action on its turn, but not both. These effects last for 1 minute. The creature can repeat the saving throw at the end of each of its turns, ending the effect on itself with a successful save.

Weakening Breath. Each creature in the area must succeed on a Strength saving throw or have disadvantage on Strength-based attack rolls, Strength checks, and Strength saving throws for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Incapacitating Breath. Each creature in the area must succeed on a Constitution saving throw or be incapacitated for one minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
