Bombardment

Upon lifting your whistling device into the air and blowing into it you summon a curse unlike any before, because quite honestly why would anyone want to make this? This curse conjures a gym coach who screams "bombardment" as they peg your enemy in the head with a red dodgeball. They must make a dexterity saving throw to dodge it every turn or 1 minute outside of combat until concentration breaks or until 1 day has passed. If they fail they have disadvantage on their first attack roll. They take 5hp of bludgeoning damage as the ball is just a rock painted red.
