Wrathful Smite

1-level Evocation

The next time you hit with a melee weapon attack during this spell’s duration, your attack deals an extra 1d6 psychic damage. Additionally, if the target is a creature, it must succeed on a Wisdom saving throw or be frightened of you until the spell ends. As an action, the creature can make a Wisdom check against your spell save DC to steel its resolve and end this spell.
