Crimson Lash

You conjure a whip of psychic energy that lashes out at a creature within range. The target must succeed on
an Intelligence saving throw or take 1d6 psychic damage and has disadvantage on its next attack roll before the end
of its next turn.

The cantrip's damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
