Crazed Hag

Innate Spellcasting. The hag's innate spellcasting ability is Charisma (spell save DC 16, +7 to hit with spell attacks). She can innately cast the following spells, requiring no material components:

At will: Vicious Mockery, Mind Sliver, Minor Illusion
3/day each: Synaptic Static, Phantasmal Killer, Mental Prison
1/day each: Psychic Scream, Feeblemind

Mimicry. The hag can mimic animal sounds and humanoid voices. A creature that hears the sounds can tell they are imitations with a successful DC 15 Wisdom (Insight]) check.

Multiattack. The hag makes two curse attacks.

Slam. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 13 (1d12 + 6) bludgeoning damage.

Curse. Ranged Spell Attack: +6 to hit, range 20/60, one target. Hit: 15 (3d6 + 4) psychic damage.

Illusory Appearance. The hag covers herself and anything she is wearing or carrying with a magical illusion that makes her look like another creature of her general size and humanoid shape. The illusion ends if the hag takes a bonus action to end it or if she dies.

The changes wrought by this effect fail to hold up to physical inspection. For example, the hag could appear to have smooth skin, but someone touching her would feel her rough flesh. Otherwise, a creature must take an action to visually inspect the illusion and succeed on a DC 20 Intelligence (Investigation) check to discern that the hag is disguised.
