Effect
You exchange your own living heart for the finely crafted heart of stone you used for the spell’s material component. Your living heart can then be stored or hidden anywhere you like, but must remain within 1 mile of you to keep the spell active, where it continues to beat for the duration. While your heart is removed in this manner, you automatically succeed on all death saving throws. If you die, but your original heart remains intact, you gain a new body with a new stone heart in 1d10 days and return to life with all your hit points. Your new body appears within 5 feet of your original heart.
While you possess a stone heart, you lose the ability to heal naturally during a short or long rest, and can only restore hit points through magical healing. If your living heart is damaged or destroyed, you are instantly slain. You can choose to end the spell as a bonus action. The spell ends automatically if you travel more than 1 mile from your living heart. When the spell ends, your own living heart instantly returns to its proper place, and the stone heart is destroyed.
