Terror Strike

As part of the action used to cast this spell, you must make a melee attack with a weapon against one creature within the spell's range, otherwise the spell fails. On a hit, the target suffers the attack's normal effects, and must succeed on a Wisdom saving throw or become frightened of you until the end of your next turn

This spell deals an additional 1d8 psychic damage when you hit with the weapon attack at 5th level, and an additional 1d8 at 11th level (2d8), and 17th level (3d8)
