BOO!

You turn to your foe, add a little magic, and scare them the best you can. Choose one creature you can see within range, the target must succeed on a Wisdom saving throw or take 1d6 psychic damage and become frightened until the end of their next turn, if they succeed the saving throw, they can't be frightened by the cantrip for the next 24 hours. Creatures that are immune to being frightened cannot be frightened by this spell.

This spell’s damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
