Rolomiel Bloodline

The Rolomiel bloodline of vampires tend to be very powerful, but also have significant weaknesses.
Vampire lords often have numerous undead beside it, usually freshly killed and animated and bent to its will. They usually fly above the battlefield using their impressive wingspan to soar above the battlefield unleashing spells of death upon its foes often unbeknownst to those below with its innate ability to become invisible.
When that fails, the vampire lord is no slouch when it comes to hand to hand combat as their very touch can kill a creature where it stands only to have it serve its new master when it falls. With its dealings with necromancy and its natural undeath, it uses these innate necromantic abilities to further its vitality and siphon the very life energy of those around them making if difficult for any to even get close to it.
Very few vampires live the millennia it takes to become a vampire lord and even fewer master their new found abilities. Though rumors say that a ritual may exist that serves as a shortcut. Even so, one must be a vampire to do anything with the ritual, all others will only become lifeless shells of their former selves. Be wary when facing this master of death as it may be the last time you are truly alive of your own free will.
In the machinations of vampires, the undead creatures vie against the living and against each other. Power is all, and the accumulation of power is the goal of these foul beings. Sometimes they rise up against their creators; on rare occasions they succeed in breaking the iron control of their "master" and slay it. These creatures can go beyond the normal vampire, and become an even more vile and horrible undead: a vampire lord. Few are ever seen, or recognized if seen. Possessing few of the weaknesses of their lesser kindred, they walk among mortals with little fear of discovery. They are the rulers of vampire communities. In a world where vampire conclaves battle against each other, the vampire lords play chess with their lesser kindred.
Vampire lords are few and far between, and each is fiercely territorial. They know that run-of-the-mill vampires cannot match their power, but another vampire lord is a definite threat. As they gain power, they become more arrogant towards those they believe pose no threat, and more fearful of any real threat to their continued existence. Thus, if a vampire lord arises in the territory of another, the newcomer is driven away or destroyed as quickly as possible. Vampire lords command hundreds of undead servants throughout their vast territories, and can have legions of vampire servants at their beck and call.
Unlike normal vampires, a vampire lord does not look the least bit unusual. It looks exactly like it did when alive and in the peak of health. It has lost the pale, hardened, almost feral look of the vampire. A vampire lord always surrounds itself with wealth and opulence, but it never forgets that the opulence is a by-product of power, not the primary goal.

Rolomiel Vampire Template

 Prerequisites: Humanoid or monstrosity killed by a Rolomiel Bloodline vampire's Bite attack
 Benefit: The game statistics of a player character transformed into a Rolomiel Vampire Spawn and then into a Rolomiel 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, traits, and actions. Attack and damage rolls for the vampire's attacks are based on Strength. The save DC for Charm is 8 + the vampire's proficiency bonus + the vampire's Charisma modifier. The character's alignment becomes lawful evil.
Damage Resistances.
Necrotic; Bludgeoning, Piercing, And Slashing From Nonmagical Weapons
Darkvision 120 Ft.
Traits.
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. (If the base creature has a natural swim speed, this effect does not apply.)
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.
Actions.
Multiattack: The Vampire makes two attacks, only one of which can be a bite Attack.
Bite: Melee Weapon Attack: Str + proficiency to hit, reach 5 ft., one willing creature, or a creature that is Grappled by the Vampire, Incapacitated, or Restrained. Hit: (1d6 + Str) piercing damage plus 7 (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.
Claws: Melee Weapon Attack: Str + proficiency to hit, reach 5 ft., one creature. Hit: 8 (2d4 + Str) slashing damage. Instead of dealing damage, the Vampire can grapple the target (escape DC based on Strength).
When a Rolomiel vampire spawn transitions into a full vampire, they also gain the following:
Shapechanger: If the vampire isn't in sun light 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.
Charm: The vampire Targets one humanoid it can see within 30 ft. 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 bit 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, provided that the sun isn't up. While outdoors, the vampire can call 3d6 wolves 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.
Legendary Actions.
Can take 3 Legendary Actions, choosing from the options below. Only one legendary action can be used at a time, and only at the end of another creature's turn. Spent legendary Actions are regained at the start of each 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.
