Any creature you touch with this spell instantly turns into a child version of themselves. They must make a wisdom saving throw,. On a success, the spell doesn't affect the targeted creature. On a failed save, however, the target's size decreases to small and their speed is a fourth of their initial speed. Additionally, they take 2d6 psychic damage and attack rolls have advantage against them. This spell has no effect on creatures larger than large, and creatures small and under remain their current size, but suffer from the other effects.
