Dusk Hag

The hag has advantage on saving throws against spells and other magical effects.

The hag's spellcasting ability is Charisma (spell save DC 15). She can innately cast the following spells, requiring no material components:

At will: detect magic, disguise self

3/day each: dream, hypnotic pattern, sleep (9d8)

1/day each: legend lore, scrying

The hag makes two Nightmare Touch attacks.

Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 5 (1d6 + 2) slashing damage.

Melee Spell Attack: +7 to hit, reach 5 ft., one creature. Hit: 18 (4d6 + 4) psychic damage. If the target is unconscious, it takes an extra 10 (3d6) psychic damage and is cursed until the hag dies or the curse is removed. The cursed creature's hit point maximum decreases by 5 (1d10) whenever it finishes a long rest.

When an unconscious creature the hag can see within 30 feet of her regains consciousness, the hag can force the creature to make a DC 15 Wisdom saving throw. Unless the save succeeds, the creature takes 11 (2d10) psychic damage, and the hag regains hit points equal to the amount of damage taken.
