The Next Thing Your Gonna Say Is...

You predict what the next thing that 1 person that you can see, and is within range is going to say, at which point the target must make a Charisma save, on a failure, they say what you predicted what they were gonna say, and they take 1d8 psychic damage. the spell fails if it doesn't understand you, you say something that the creature obviously wouldn't say, eg: a loyal guardsman "I'm gonna betray the king and help you overthrow the kingdom", and has no effect on the feelings of the target. the creature also on a failure has disadvantage on the first attack roll if it targets you if it goes after you in the initiative order, but the creature can counter this by not attacking you.

This spells power increases to 2d8 psychic damage at 5th level, 3d8 at 11th level, and 4d8 at 17th level, and starting at 11th level, upon failure of the first save, the target must make a wisdom save or have to attack the spellcaster with their first attack.
