You whisper a malevolent curse that only one creature of your choice within range can hear, wracking it with terrible pain. The target must succeed on a Wisdom saving throw or take 1d4 psychic damage and have disadvantage on the next attack roll it makes before the end of its next turn as infernal voices haunt its mind.   At Higher Levels: The spell's damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4).  

Special Notes: Infernal Whisper directly channels the Abyssal Cult's affinity for dark magic and their willingness to embrace malevolent forces to achieve their ends. It represents the sect's more sinister aspects, using fear and pain as weapons against their enemies. This cantrip introduces an element of psychological warfare to gameplay, allowing characters to weaken foes and sow discord through fear.
