The leannán sídhe uses its bonus action and action to target a humanoid it can see within 30 feet that can both see it and hear it. The target makes a DC 18 Charisma saving throw or falls madly in love with the leannán sídhe and becomes charmed. Whenever the charmed target makes an ability check, attack roll, or saving throw that is not against the leannán sídhe, it gains a +1d8 bonus. While the target is charmed by the leannán sídhe, once per day the fey can give it any command short of an activity that would result in certain death. When the leannán sídhe does so, the charmed target may make a DC 18 Charisma saving throw to resist. At the end of every long rest the charmed target makes a Charisma saving throw against the leannán sídhe (DC 10 + 1 per previous successful save) or its Wisdom score is permanently reduced by 1. The charmed target dies if this reduces its Wisdom score to 0. A target remains charmed until it makes 5 successful consecutive saving throws, the leannán sídhe dies, or the fey chooses a new humanoid to charm with Inspired Infatuation.
