Cursed Cookie Jar

You wave your hand in a theatrical fashion, causing a cookie jar to appear in it. The jar then flies towards a target of your choice. That creature must make a Wisdom saving throw. On a failed saving throw the cookie jar lands on their head. On a successful saving throw, they resist its charms and the cookie jar shatters on the ground. The next confection spell to target the affected creature has advantage to hit and the creature has disadvantage on saving throws against that spell. The affected creature takes an extra 2d8 psychic damage
