Sneaky Quack

If a character can catch an ally when they are unable to defend themselves effectively from their healing, they can heal a vital spot for extra healing. The character's heal heals extra damage anytime their target would be denied a Dexterity bonus to AC (whether the target actually has a Dexterity bonus or not), or when the character flanks their target. This extra healing is equal to 1d6 per die of your sneak attack. This extra healing is precision healing.
