Emotional Blackmail

You touch a creature within range and force them to make a Charisma saving throw. On failure you declare an emotion to steal from the target. The material component used in casting the spell now contains the declared emotion of the target. The target loses any ability to feel or empathize with said emotion until the object is destroyed.

At higher levels. When you cast this spell using a 7th level spell slot, you may steal 2 emotions. When you use a 8th level spell slot, you may steal 3 emotions. When you use a 9th level spell slot, the material component disintegrates and a single emotion is lost forever.
