Baba Yaga

Innate Spellcasting. Baba Yaga's innate spellcasting ability is Charisma (spell save DC 18, +8 to hit with spell attacks). She can innately cast the following spells, requiring no material components:

At will: detect magic, magic missile

2/day each: plane shift (self only), ray of enfeeblement, sleep

Magic Resistance. Baba Yaga has advantage on saving throws against spells and other magical effects.

Horrific Appearance. Any humanoid that starts its turn within 30 feet of the Baba Yaga and can see the hag's true form must make a DC 18 Wisdom saving throw. On a failed save, the creature is frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, with disadvantage if Baba Yaga is within line of sight, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it' the creature is immune to to the hag's horrific appearance for the next 24 hours. Unless the target is surprised or the revelation of Baba Yaga's true form is sudden, the target can avert its eyes and avoid making the initial saving throw. Until the start of its next turn, a creature that averts its eyes has disadvantage no attack rolls against the hag.

Mimicry Baba Yaga can mimic animal sounds and humanoid voices. A creature that hears the sounds can tell the are imitations with a successful DC 22 Wisdom (insight) check.

Claws.(Hag Form Only). Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) slashing damage.

Change Shape. The hag magically polymorphs into a Small or Medium female humanoid, or back into her true form. Her statistics are the same in each form. Any equipment she is wearing or carrying isn't transformed. She reverts to her true form if she dies.

Etherealness. The hag magically enters the Ethereal Plane from the Material Plane, or vice versa. To do so, the hag must have a heartstone in her possession.

Nightmare Haunting (1/Day). While on the Ethereal Plane, the hag magically touches a sleeping humanoid on the Material Plane. A protection from evil and good spell cast on the target prevents this contact, as does a magic circle. As long as the contact persists, the target has dreadful visions. If these visions last for at least 1 hour, the target gains no benefit from its rest, and its hit point maximum is reduced by 5 (1d10). If this effect reduces the target's hit point maximum to 0, the target dies, and if the target was evil, its soul is trapped in the hag's soul bag. The reduction to the target's hit point maximum lasts until removed by the greater restoration spell or similar magic.

Death Glare Baba Yaga targets one frightened creature she can see within 30 feet of her. If the target can see Baba Yaga, it must succeed on a DC 22 Wisdom saving throw against this magic or drop to 0 hit points.
