Timeheal

This spell rewinds the body of the target creature
backward in time to a point where it was in better
health. The time reversal is up to five minutes and their
hit points are reset to the amount at that point in time.
The target creature must succeed on a Constitution
save or be sickened for an amount of time equal to that
which was turned back.
Timeheal will not raise the dead as it only affects the
body and not the spirit. It will only reverse any damage
done to the body.
At Higher Levels. When you cast this spell using a spell
slot of 5th level or higher, one additional minute can be
reversed for each slot above 4th.
