Spell Finesse

Your spells can benefit from your sneak attack class feature.  You gain the following:

• Increase your Intelligence, Wisdom, or Charisma score by 1, to a maximum of 20.
• When you hit a creature with a spell attack that deals damage, you can add your sneak attack damage to the attack if the creature qualifies as a sneak attack target and you haven’t already used your sneak attack in the current turn.
• When you force a creature to make a saving throw against a spell you cast, if the creature is a viable sneak attack target and if you haven’t yet used your sneak attack this turn, you can increase the spell save DC by half of your total sneak attack dice (rounded down). You can only increase the spell’s  DC for one creature affected by the spell regardless of how many creatures the spell targets.
