Cinder Hag

Magic resistant. The hag has advantage on saves against spells and other magical effects

Innate Spellcasting. The hag's innate spellcasting ability is Charisma (spell save DC 15 +6 to hit). She can innately cast the following spells, requiring no material components:

At will: burning hands, faerie fire, chromatic orb, hellish rebuke, fire bolt

3/day each: heat metal, scorching ray

1/day: wall of fire

Claws. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 11 (2d6 + 4) slashing damage and 3 (1d6) fire 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.

Fiery escape. As a bonus action or a reaction upon taking damage a cinder hag can magically teleport to the nearest open flame of any size within 120 feet
