You learn to control your arcane or divine energies to prevent death on those you use them on, granting you the following benefits:

• Increase your Intelligence, Wisdom, or Charisma score by 1, to a maximum of 20.
• You learn the spare the dying cantrip.
• As a bonus action, or as an action, you may infuse one spell you cast before the beginning of your next turn with non-lethal intent, causing a creature hit by it to become unconscious and stable instead of dying if brought to 0 hit points. This effect does not work on undead or constructs.
