Transfer Excess Body Fat

Transmutative energy washes over a creature of your choice that you are aware of, creating a link between your physical form and theirs. The target must make a Constitution saving throw which is modified by how well you know the target and the sort of physical connection you have to it.

On a successful save, the target isn't affected, and you can't use this spell against it again for 24 hours.

On a failed save, the target gains the Prone condition, immediately falling over.  Even if the target subsequently stands up, the penalties of being Prone remain until the spell ends.

To cast this spell, the somatic components of this spell are some form of exercise such as swimming or hiking which must be maintained for at least 1 hour.  The spell can be maintained indefinitely by spending one hour each day doing likewise somatic exercise.

At dawn each morning, the target makes another Constitution saving throw.  On a successful save, the spell ends.  On a failed save, the target loses 1 point of Strength and 1 point of Constitution, and gains 1kg of body fat, whilst the spellcaster gains 1 point of Strength and 1 point of Constitution, and loses 1kg of body fat, as the strength and fitness of the target is transferred to the spellcaster.

If the target's Strength or Constitution are reduced to 0, the target dies.
