Heartthrob

Wondrous item, rare (requires attunement)
  A Biomancers guide to dating: 1. Make yourself an offlay good wand that can beat in time with your desired partner’s heart. 2. Try some pick-up lines and see what gets their heart beating quickly. 3. Keep the gruesome heart-wand hidden or you’ll scare them off. 4. Profit.
  While holding this wand you can cast the spare the dying cantrip at will. To do so you must lay the wand on the target before performing a quick burst of CPR on the wand’s heart.
  Heartstrings. As a bonus action you can point the wand at a target you can see within 60 feet. The target must succeed on a DC 15 Wisdom saving throw or become linked to heartthrob for the next 10 minutes. A creature that succeeds on the saving throw or becomes unlinked from heartthrob can’t be linked again for the next 24 hours. Creatures without hearts automatically succeed on this saving throw.
  For the duration the target is linked to the wand, you have advantage on Wisdom (Insight) checks against the linked creature, which has disadvantage or Charisma (Deception) checks against you. In addition, you can use the Skip a Beat and Infarction features, targeting the linked creature.
  Skip a Beat. As a reaction when you see the linked creature makes an attack, you can squeeze the heart, imposing disadvantage on the attack. After the attack is concluded, the linked creature can repeat the Wisdom saving throw, unlinking itself on a success.
  Infarction. As an action you can cease blood flow to the linked creature’s heart. It must make a DC 15 Constitution saving throw, taking 6d8 necrotic damage on a failure, or half as much damage on a success. After you do so, the creature becomes unlinked from the heart and you can’t use Infarction or Skip a Beat again until the following dawn.
