Dungeons & Dragons 5e Element 133 Class Feature: Emotional Damage

You gain the ability to figure out what your target is most sensitive about and exploit it. When you take this action, you may select a target that can hear and understand you. The target must make a Charisma saving throw of DC 8 + your proficiency bonus + your Charisma modifier. If they fail, they take a number of d4s equal to your tier plus your Charisma modifier worth of psychic damage. The target then takes disadvantage on their next turn. You may use this ability a number of times equal to your Charisma modifier. This ability resets after a long rest.
