When you are dealt damage that would reduce you to 0 hit points you may, as a reaction, conjure a dart of force which flies into a target you can see in range.
You make a ranged spell attack. On a hit, they are infected with a magical disease that will create a clone of you out of their flesh. At the end of the targets next turn they take 10d10 necrotic damage. If they die within one minute of being hit with the dart the magical disease activates. When the spell activates a small baby form of yourself bursts from their abdomen and grows to your previous full size, weight, and age by the end of the round. You have half your maximum HP, any natural diseases are cured, and all exhaustion is removed.
When the magical disease activates your soul is transferred from wherever it is into this new body. It does this regardless of whether you are alive, or conscious. Even if you have recovered consciousness your soul is still transferred and your old body instantly dies. None of your gear is transferred.
If the target does not die within the first minute the disease dissipates and the spell ends.
