Vampire Lesser

The player as a vampire, here as the vampire spawn or lesser vampire, who then can turn into a real vampire/greater vampire.

PLAYER CHARACTERS AS VAMPIRES

The game statistics of a player character transformed into a vampire spawn and then a vampire don’t change, except that the character’s Strength, Dexterity, and Constitution scores become 18 if they aren’t higher. In addition, the character gains the vampire’s damage resistances, darkvision 120 (you might need to set it manually if it is over 120 ft), traits, and actions. Attack and damage rolls for the vampire’s attacks are based on Strength. The character’s alignment becomes lawful evil, and the DM might take control of the character until the vampirism is reversed with a wish spell or the character is killed and brought back to life.
(you have to change Str, Dex and Con yourself in your Character sheet)

Undead. your creature type is now Undead rather then Humanoid or Fay, you do not age and you do not require air to breathe.

Regeneration. The vampire regains 10 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 when it ends its turn in running water.

Stake to the Heart. The vampire is destroyed if a piercing weapon made of wood is driven into its heart while it is incapacitated in its resting place.

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.

Multiattack. The vampire makes two attacks, only one of which can be a bite attack. Only with Claw and Bite attack.

Claws. Melee Weapon Attack: reach 5 ft., one creature. Hit:  2d4 slashing damage. Instead of dealing damage, the vampire can grapple the target.

Bite. Melee Weapon Attack: reach 5 ft., one willing creature, or a creature that is grappled by the vampire, incapacitated, or restrained. Hit: 1d6 piercing damage plus 2d6 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.

Awakened to an endless night, vampires hunger for the life they have lost and sate that hunger by drinking the blood of the living. Vampires abhor sunlight, for its touch burns them. They never cast shadows or reflections, and any vampire wishing to move unnoticed among the living keeps to the darkness and far from reflective surfaces.

Dark Desires. Whether or not a vampire retains any memories from its former life, its emotional attachments wither as once-pure feelings become twisted by undeath. Love turns into hungry obsession, while friendship becomes bitter jealousy. In place of emotion, vampires pursue physical symbols of what they crave, so that a vampire seeking love might fixate on a young beauty. A child might become an object of fascination for a vampire obsessed with youth and potential. Others surround themselves with art, books, or sinister items such as torture devices or trophies from creatures they have killed.

Born from Death. Most of a vampire’s victims become vampire spawn — ravenous creatures with a vampire’s hunger for blood, but under the control of the vampire that created them. If a true vampire allows a spawn to draw blood from its own body, the spawn transforms into a true vampire no longer under its master’s control. Few vampires are willing to relinquish their control in this manner. Vampire spawn become free-willed when their creator dies. Few rare vampires are created from the magic of a Crimson stone, a magic item with the power to give some people the curse of vimpirism making them into a free willed vampire spawn (lesser vampire) who if they rink a vampires blood become a greater vampire. and even rares is a humanoid turned into a vampire from a succubus in love, they become greater vampires from the start, and it is said that this is how the first vampires came to be.

Chained to the Grave. Every vampire remains bound to its coffin, crypt, or grave site, where it must rest by day. If a vampire didn’t receive a formal burial, it must lie beneath a foot of earth at the place of its transition to undeath. A vampire can move its place of burial by transporting its coffin or a significant amount of grave dirt to another location. Some vampires set up multiple resting places this way.

Undead Nature. Neither a vampire nor a vampire spawn requires air.
