Cruel Caster

You are expert at wounding your foes with spells. You gain the following benefits:

• Increase your Intelligence, Wisdom, or Charisma score by 1, to a maximum of 20.
• Whenever you damage a creature with a spell, you can choose to halve the creature's wound threshold when determining if it suffers a wound. Once you have used this feature, you cannot do so again until you finish a short or long rest.
