Friendly Joybuzzer

This tin ring houses a small circular device with a red button. You have advantage on Sleight of Hand checks made to hide the _friendly joybuzzer_. Once you are attuned to this magic item, whenever a creature presses the button (even inadvertently through a handshake) for the next minute it becomes happier and friendlier towards you. For the duration, you gain an expertise die on Charisma checks against the creature. If the creature sees the joybuzzer being used or recognizes it as a magical item, it immediately realizes that you used magic to influence its mood and may become hostile toward you. Alternatively, once you are attuned to this magic item, while you are shaking hands with a creature you can choose to destroy the _friendly joybuzzer_. Make a melee spell attack with _advantage_ , using your highest mental ability score as your spellcasting ability score. On a successful hit, you target the creature as if you had cast __shocking grasp_ , treating each damage die as if you had rolled the maximum amount.
