Curse of Youth

This spell reverses time for a humanoid that you can see within range until it becomes a helpless infant. An unwilling creature must make a Wisdom saving throw to avoid the effect. The spell has no effect on a shapechanger, a creature that does not naturally experience infancy, or a creature with 0 hit points.

The target retains all of its game statistics except its base movement speed, which becomes 10 feet, and hit points, which becomes 1. It retains its alignment and personality.
