Vampire Warlock

Shapechanger. If the vampire isn't in sunlight or running water, it can use its action to polymorph into a Tiny bat or a Medium cloud of mist, or back into its true form.

While in bat form, the vampire can't speak, its walking speed is 5 feet, and it has a flying speed of 30 feet. Its statistics, other than its size and speed, are unchanged. Anything it is wearing transforms with it, but nothing it is carrying does. It reverts to its true form if it dies.

While in mist form, the vampire can't take any actions, speak, or manipulate objects. It is weightless, has a flying speed of 20 feet, can hover, and can enter a hostile creature's space and stop there. In addition, if air can pass through a space, the mist can do so without squeezing, and it can’t pass through water. It has advantage on Strength, Dexterity, and Constitution saving throws, and it is immune to all nonmagical damage, except the damage it takes from sunlight.

Legendary Resistance (3/Day). If the vampire fails a saving throw, it can choose to succeed instead.

Misty Escape. When it drops to 0 hit points outside its resting place, the vampire transforms into a cloud of mist (as in the Shapechanger trait) instead of falling unconscious, provided that it isn't in sunlight or running water. If it can't transform, it is destroyed.

While it has 0 hit points in mist form, it can't revert to its vampire form, and it must reach its resting place within 2 hours or be destroyed. Once in its resting place, it reverts to its vampire form. It is then paralyzed until it regains at least 1 hit point. After spending 1 hour in its resting place with 0 hit points, it regains 1 hit point.

Regeneration. The vampire regains 20 hit points at the start of its turn if it has at least 1 hit point and isn't in sunlight or running water. If the vampire takes radiant damage or damage from holy water, this trait doesn't function at the start of the vampire's next turn.

Spider Climb. The vampire can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.

Vampire Weaknesses. The vampire has the following flaws:

Forbiddance. The vampire can't enter a residence without an invitation from one of the occupants.

Harmed by Running Water. The vampire takes 20 acid damage if it ends its turn in running water.

Stake to the Heart. If a piercing weapon made of wood is driven into the vampire's heart while the vampire is incapacitated in its resting place, the vampire is paralyzed until the stake is removed.

Sunlight Hypersensitivity. The vampire takes 20 radiant damage when it starts its turn in sunlight. While in sunlight, it has disadvantage on attack rolls and ability checks.

Innate Spellcasting. The vampire’s innate spellcasting ability is Charisma. It can innately cast the following spells (spell save DC 17), requiring no material components:

At will: disguise self, mage armor (self only)

Spellcasting. The vampire is a 9th-level spellcaster. Its spellcasting ability is Charisma (spell save DC 17, +9 to hit with spell attacks). It regains its expended spell slots when it finishes a short or long rest. It knows the following warlock spells:

Cantrips (at will): chill touch, eldritch blast, toll the dead

1st–5th level (2 5th-level slots): armor of agathys, blight, blindness/deafness, command, fireball, flame strike, fly, hold person, negative energy flood, wall of fire

Dark One’s Blessing. When the vampire reduces a hostile creature to 0 hit points, it gains 13 temporary hit points (Charisma modifier + warlock level).

Dark One’s Own Luck (Recharges after a Short or Long Rest). When the vampire makes an ability check or saving throw, it can add a d10 to the roll. It can do this after the roll is made but before any of the roll’s effects occur.

Cloak of Flies (Recharges after a Short or Long Rest). As a bonus action, the vampire can surround itself with a magical aura that looks like buzzing flies. The aura extends 5 feet from them in every direction, but not through total cover. It lasts until the vampire is incapacitated (or reduced to 0 hp) or they dismiss it as a bonus action. The aura grants the vampire advantage on Charisma (Intimidation) checks but disadvantage on all other Charisma checks. Any other creature that starts its turn in the aura takes 4 poison damage (Charisma modifier).

Multiattack. (Vampire Form Only). The vampire makes two attacks, only one of which can be a bite attack.

Greatsword (Pact Weapon, Vampire Form Only). Melee Weapon Attack: +9 to hit, reach 5 ft., one creature. Hit: 11 (2d6 + 4) slashing damage, magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.

Unarmed Strike (Vampire Form Only). Melee Weapon Attack: +9 to hit, reach 5 ft., one creature. Hit: 8 (1d8 + 4) bludgeoning damage. Instead of dealing damage, the vampire can grapple the target (escape DC 18).

Bite. (Bat or Vampire Form Only). Melee Weapon Attack: +9 to hit, reach 5 ft., one willing creature, or a creature that is grappled by the vampire, incapacitated, or restrained. Hit: 7 (1d6 + 4) piercing damage plus 10 (3d6) necrotic damage. The target's hit point maximum is reduced by an amount equal to the necrotic damage taken, and the vampire regains hit points equal to that amount. The reduction lasts until the target finishes a long rest. The target dies if this effect reduces its hit point maximum to 0. A humanoid slain in this way and then buried in the ground rises the following night as a vampire spawn under the vampire's control.

Charm. The vampire targets one humanoid it can see within 30 feet of it. If the target can see the vampire, the target must succeed on a DC 17 Wisdom saving throw against this magic or be charmed by the vampire. The charmed target regards the vampire as a trusted friend to be heeded and protected. Although the target isn't under the vampire's control, it takes the vampire's requests or actions in the most favorable way it can, and it is a willing target for the vampire's bite attack.

Each time the vampire or the vampire's companions do anything harmful to the target, it can repeat the saving throw, ending the effect on itself on a success. Otherwise, the effect lasts 24 hours or until the vampire is destroyed, is on a different plane of existence than the target, or takes a bonus action to end the effect.

Children of the Night (1/Day). The vampire magically calls 2d4 swarms of bats or rats (swarm of bats, swarm of rats), provided that the sun isn't up. While outdoors, the vampire can call 3d6 wolves (wolf) instead. The called creatures arrive in 1d4 rounds, acting as allies of the vampire and obeying its spoken commands. The beasts remain for 1 hour, until the vampire dies, or until the vampire dismisses them as a bonus action.

Gaze of Two Minds. The vampire can touch a willing humanoid and perceive through its senses until the end of the vampire's next turn. As long as the creature is on the same plane of existence as the vampire, it can use its action on subsequent turns to maintain this connection, extending the duration until the end of its next turn. While perceiving through the other creature’s senses, the vampire benefits from any special senses possessed by that creature, and the vampire is blinded and deafened to its own surroundings.

Ghostly Gaze (Recharges after a Short or Long Rest). The vampire can use its action to gain the ability to see through solid objects to a range of 30 feet, retaining its darkvision. This special sight lasts for 1 minute or until its concentration ends (as if the vampire were concentrating on a spell). During that time, you perceive objects as ghostly, transparent images.

Pact of the Blade. The vampire can use its action to create a pact weapon in their empty hand. They can choose the form that this melee weapon takes each time they create it and they are proficient with it while they wield it. This weapon counts as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage. The pact weapon disappears if it is more than 5 feet away from the vampire for 1 minute or more. It also disappears if the vampire uses this feature again, if they dismiss the weapon (no action required), or if the vampire dies.

The vampire 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. The vampire regains spent legendary actions at the start of its turn.

Move. The vampire moves up to its speed without provoking opportunity attacks.

Unarmed Strike. The vampire makes one unarmed strike.

Bite.(Costs 2 Actions). The vampire makes one bite attack.
