Heaven’s Clockwork Heart
Wondrous Item, uncommon
This heart-shaped amulet with a winding key has 3 charges. While holding it to your chest and using an action to wind the key, you can expend 1 charge for the following properties.
Assistive Heartbeat. The amulet sends a magic signal to your heart that lasts for 1 day to compensate for Organ Failure, Heart Palpitations, or other heart-related conditions. This stops any form of deterioration in condition for 1 day and gives you +2 on all related saving throws. This function lasts a full day as long as the amulet remains within 1 foot of your chest.
Heart Goes Out. You use your action to touch a living creature, and you take 1d4 necrotic damage, which can’t be reduced in any way, and the creature that you touch regains a number of hit points equal to twice the necrotic damage you take.
Give Me Your Heart. You use your action to touch a willing living creature. The creature that you touch takes 2d4 necrotic damage, which can’t be reduced in any way, and you gain a number of temporary hit points equal to half the necrotic damage.
The amulet regains 1 expended charge daily after a long rest.
