Whisper of Betrayal

You whisper a lie in the voice of someone the target trusts, a promise of the knife already waiting at its back. Choose one creature you can see within range that can hear you. The target must succeed on a Wisdom saving throw or take 1d6 Psychic damage, and the next attack roll made against it before the start of your next turn has Advantage as the target flinches from friend and foe alike.

Cantrip Upgrade. The damage increases by 1d6 when you reach levels 5 (2d6), 11 (3d6), and 17 (4d6).
