Dagger

Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 7 (1d4 + 5) piercing damage.

Charm

The lorelei targets one humanoid she can see within 30 feet of her. If the target can see or hear the lorelei, it must succeed on a DC 17 Wisdom saving throw against this magic or be charmed by the lorelei. The charmed target regards the lorelei as its one, true love, to be heeded and protected. Although the target isn't under the lorelei's control, it takes the lorelei's requests or actions in the most favorable way it can. Each time the lorelei or her companions cause the target to take damage, directly or indirectly, it repeats the saving throw, ending the effect on itself on a success. Otherwise, the effect lasts 24 hours or until the lorelei is killed, is on a different plane of existence than the target, or takes a bonus action to end the effect.

Stunning Glance

The lorelei mentally disrupts a creature within 30 feet with a look. The target must succeed on a DC 17 Wisdom saving throw or be stunned for 2 rounds. Anyone who successfully saves against this effect cannot be affected by it from the same lorelei for 24 hours.
