Collector's Jar

You create the illusion of a tall, pale creature that reaches into the mind of one target within range. The target must make an intelligence saving throw. On a failure, the target takes 5D6 psychic damage, and believes themselves to be trapped in a glass jar, causing them to be Restrained. On a successful save, the target takes half damage, and isn’t restrained. At the end of its turn, the target may repeat its saving throw, ending the effect early on a success.

At Higher Levels: For each level cast over 3rd, increase the damage by 1D6 Psychic damage.
