Compelling Blade

You flourish the weapon used in the spell’s casting and make a melee attack with it against one creature within 5 feet of you. On a hit, the target suffers the weapon attack’s normal effects and they are compelled to attack you. If the target attacks a creature that isn't you before the start of your next turn, it takes 1d8 psychic damage and the spell ends.

This spell’s damage increases when you reach certain levels. At 5th level, the melee attack deals an extra 1d8 psychic damage to the target on a hit, and the damage the target takes for attacking a creature other than you becomes to 2d8. Both damage rolls increase by 1d8 at 11th level (2d8 and 3d8) and again at 17th level (3d8 and 4d8).
