Traits

Amphibious. The Lamia can breathe air and water.

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

Multiheaded Prowess. The Lamia has seven heads. For each head beyond one, it gains an extra reaction that can be used only for opportunity attacks. Whenever the Lamia takes 30 or more damage in a single turn, one of its heads dies. If all its heads die, the Lamia dies.

Regeneration. The Lamia regains 15 hit points at the start of its turn for each of its living heads. If the Lamia takes fire or radiant damage, this trait doesn't function at the start of its next turn. The Lamia dies only if it starts its turn with 0 hit points and doesn't regenerate.

Swallow Whole. The Lamia can swallow Large or smaller creatures. A swallowed creature is blinded and restrained, has total cover against attacks and effects outside the Lamia, and takes 28 (8d6) acid damage at the start of each of the Lamia's turns. The Lamia can have up to two creatures swallowed at a time.

Shapechanger. The Lamia can use its action to polymorph into a Medium female humanoid or back into its true form. Its statistics, other than its size, are the same in each form. Its equipment isn't transformed. It reverts to its true form if it dies.

Water Manipulation. The Lamia can cast the control water spell at will, without requiring components. Its spellcasting ability is Charisma (spell save DC 19).

Innate Spellcasting. The Lamia's innate spellcasting ability is Charisma (spell save DC 19, +11 to hit with spell attacks). It can innately cast the following spells, requiring no material components:

At will: charm person, detect thoughts, invisibility, major image

3/day each: suggestion, hypnotic pattern, lightning bolt (as a 5th-level spell)

1/day each: mass suggestion, chain lightning

Actions

Multiattack. The Lamia makes as many Bite attacks as it has heads.

Bite. Melee Weapon Attack: +12 to hit, reach 10 ft., one target.

Hit: 17 (2d8 + 6) piercing damage plus 10 (3d6) poison damage.

Constrict. Melee Weapon Attack: +12 to hit, reach 15 ft., one Large or smaller creature.

Hit: 20 (3d8 + 6) bludgeoning damage, and the target is grappled (escape DC 18). Until this grapple ends, the target is restrained, and the Lamia can't constrict another target.

Breath of Enchantment (Recharge 5–6). The Lamia exhales a magical mist in a 60-foot cone. Each creature in that area must make a DC 19 Wisdom saving throw. On a failed save, the creature is charmed by the Lamia for 1 hour. While charmed in this way, the creature regards the Lamia as a trusted friend and is under its control. The charmed target obeys the Lamia's verbal or telepathic commands. If the target suffers any harm from the Lamia or receives a suicidal command, it can repeat the saving throw, ending the effect on a success.

Wing Buffet. Melee Weapon Attack: +12 to hit, reach 15 ft., all creatures in a 15-foot radius.

Hit: 19 (3d8 + 6) bludgeoning damage. Creatures must succeed on a DC 18 Strength saving throw or be knocked prone and pushed 10 feet away.

Bonus Actions

Mist Form. The Lamia transforms into a misty cloud until it reverts to its true form as a bonus action. In mist form, the Lamia can't take any actions, speak, or manipulate objects. It is weightless, gains a flying speed of 40 feet, can hover, and can enter a hostile creature's space. In addition, if air can pass through a space, the mist can do so without squeezing. While in mist form, the Lamia is immune to nonmagical damage, and it has advantage on Strength, Dexterity, and Constitution saving throws.

Reactions

Reactive Heads. For each head the Lamia has beyond one, it gets an extra reaction that can be used only for opportunity attacks.

Parry. The Lamia adds +5 to its AC against one melee attack that would hit it. To do so, the Lamia must see the attacker and be wielding no weapons.

Legendary Actions

The Lamia can take 2 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. The Lamia regains spent legendary actions at the start of its turn.

- Move. The Lamia moves up to half its speed without provoking opportunity attacks.

- Attack. The Lamia makes one Bite or Constrict attack.

- Cast a Spell (Costs 2 Actions). The Lamia casts one spell from its Innate Spellcasting feature.

Lore

A medium-sized creature with the body of a snake and the head of a dog.

Lamia is a medium-sized creature with the body of a snake and the head of a dog. Some legends categorize this creature as a dragon. According to tales, the mouth of this monster can open so wide that it can swallow a person or animal in a single gulp. Its body is covered with yellow snake scales that can stretch to significant sizes when swallowing.

As it ages, a Lamia can grow additional heads; with each new head, its strength and wisdom increase. Typically, a Lamia can grow up to nine heads and acquire new magical abilities. In some stories, it's mentioned that the Lamia has wings that allow it to fly and attack its prey from the air—usually membranous wings like those of a bat.
