Tether

Choose one creature that you can see within range to make a Wisdom saving throw. If it fails, the target cannot use its movement to move more than 30 feet away from you for the duration. If the target moves more than 30 feet from you another way, the spell ends. The next time you would take damage during the spell's duration, you instead take only half damage and the target takes force damage equal half the triggering damage as well. As soon as the target takes damage this way, the spell ends.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, you instead take no damage and the target takes damage equal to all the triggering damage. The spell then ends as normal.
