While often considered divine magic, a devoted student of magic can learn the faith-based techniques needed to cast this spell without a connection to the divine. 

Grants one chance to endure when HP reaches 0. When an attack, impact, spell, or other event would put you at 0 HP, you instead stay at 1 HP. The spell's protection is then broken. 

Intended to grant the dying a few moments for a final farewell. Tears are shed for the sake of the living, more so than the deceased.
