 Legendary Resistance (3/Day). If Auntie HIlda fails a saving throw, she can choose to succeed instead.

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

Magic Weapons. Auntie HIlda's weapon attacks are magical.

Auntie Hilda can make three claw attacks, cast a spell, or use one of her abilities.

Claws.(Hag Form Only). Melee Weapon Attack: +13 to hit, reach 5 ft., one target. Hit: 15 (2d8 + 6) 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.

Hilda’s Eye of Avarice (Recharge 6).Hilda grips the shriveled, fossilized eye of an Elder Brain and channels her dream devouring power through it. All creatures in a 30ft radius must make a charisma saving throw or take 10d8 psychic damage and are stunned. On each creatures turn they take 5d8 psychic damage and may make a new saving throw at the end of their turn, ending the damage and stunned condition on a success. During this time their mind is devoured by perverse twisting of their greatest desires destroying them. If a creature succeeds on the initial saving throw they take half damage and are not stunned. Creatures immune to charmed effects are not affected by this ability

Auntie Hilda can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature’s turn. Auntie Hilda regains spent legendary actions at the start of her turn.

Claws.(Hag Form Only). Melee Weapon Attack: +13 to hit, reach 5 ft., one target. Hit: 15 (2d8 + 6) slashing damage.

Cantrip. Auntie Hilda casts a cantrip or uses an at-will spell.
