Blackmail Get Good Noob

On use, you will create an image of a target family in the palm of your hand. The target must make a Wisdom saving throw. If the saving throw fails, you add an advantage to your persuasion check. If it succeeds the image immediately gets burned up. After the spell ends, the target will know that they were affected by a spell.

1st level only 1 target at a time but after every level you can add 1 additional target, so like at level 2, you can affect 2 targets at the same time.
