Merciful Spellcasting

You have trained your magic to be precise. You are able to wield its force with restraint enough to merely incapacitate your foes, rather than kill. You gain the following benefits:

• Increase your Intelligence, Wisdom, or Charisma score by 1, to a maximum of 20.

• When you cast a spell, you can choose to cast it non-lethally. A creature reduced to 0 hit points by that spell's damage is unconscious but stable. That creature wakes up when they regain hit points, and regains 1 hit point in 1d4 hours if not healed in that time. If that spell summons or charms a creature, then this also applies to damage done by that creature. This cannot apply to a spell or effect that triggers when it brings a creature to 0 hit points (such as Finger of Death's zombification or Disintegrate disintegrating).
