Tears of Denial

You grip your holy symbol tightly and recall a pitiful tale of sorrow and mourning. Then, placing your relic upon one willing creature- including the caster themselves -you imbibe a blessing upon said creature. When this creature takes damage that would normally reduce its hit points to 0, the spell is triggered and they are instead left with 1 hit point. Only one creature can be under this spell's effect at any given time, casting this spell again will remove its effect from the previous recipient.

This spell can be cast on creatures with only 1 hit point, but any damage the creature takes will reduce their hit points to 0 and end the spell.
