Distracting Sound

You create loud illusory sounds in the mind of one creature you can see within range, disrupting its ability to cast or concentrate on spells. The target must succeed on a wisdom saving throw or be affected by the spell. While under the effects of this spell, whenever the creature casts a spell of 1st level or higher, it must make a constitution saving throw against your spell save DC. If it fails, it does not cast the spell and the spell slot is wasted. If it succeeds, the spell is cast as normal. In addition, at the beginning of each of its turns while it is concentrating on a spell and while it is under the affects of this spell, it must make a concentration saving throw against your spell save DC. If it fails, its concentration is broken.
