Dry Cough

You utter an ancient curse known only to the cruelest grandmothers and target one creature you can see within range.

"Your lungs are now as dry as the party's roleplay skills."

The target feels all moisture vanish from their throat and must succeed on a Constitution saving throw or take 1d4 psychic damage and spend its next turn suffering from the World's Most Annoying Cough™.

While affected, the creature:

• Has disadvantage on its next Charisma check.
• Cannot begin a sentence without coughing at least once.
• Is magically compelled to say, "I swear I had water a second ago."

At Higher Levels. The damage increases to 2d4 at 5th level, 3d4 at 11th level, and 4d4 at 17th level.
