Multiattack. The hag makes two claw attacks.

Claw. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 17 (3d8 + 4) slashing damage plus 9 (2d8) poison 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.

Mud Form (1/Day). When the hag takes damage she takes on a mud form. While in this form, the hag has Resistance to nonmagical damage (including the triggering damage), and advantage on Strength, Dexterity, and Constitution saving throws. The hag can pass through small holes, narrow openings, and even mere cracks. While in this form, the hag can't talk, manipulate objects, attack or cast spells. This form lasts for 1 minute, or until the hag dismisses it as a bonus action. If the hag is in a muddy terrain, she becomes hidden and requires a DC 20 Wisdom (Perception) check to spot.

Claw Attack. The hag makes one claw attack.

Summon Muddle (Costs 2 Actions). The hag reaches into the swampy muck and pulls forth an oozing puddle of mud. The muddle appears in an unoccupied space within 5 feet of the hag and acts as her ally. It remains for 1 minute, until it or the hag dies, or until the hag dismisses it as an action.

Cast a Spell (Costs 3 Actions). The hag uses her innate spellcasting as normal.
