Avatar of Erberus Umbeal

Shapechanger. If Erberus isn’t in sunlight, he can use his action to polymorph into a Tiny bat, a Medium wolf, or a Medium cloud of mist, or back into his true form.

While in bat or wolf form, Erberus can’t speak. In bat form, his walking speed is 5 feet, and he has a flying speed of 30 feet. In wolf form, his walking speed is 40 feet. His statistics, other than his size and speed, are unchanged. Anything he is wearing transforms with him, but nothing he is carrying does. He reverts to his true form if he dies.

While in mist form, Erberus can’t take any actions, speak, or manipulate objects. He 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 he can’t pass through water. He has advantage on Strength, Dexterity, and Constitution saving throws, and he is immune to all nonmagical damage, except the damage he takes from sunlight.

Legendary Resistance (4/Day). If Erberus fails a saving throw, he can choose to succeed instead.

Misty Escape. When Erberus drops to 0 hit points outside his coffin, he transforms into a cloud of mist (as in the Shapechanger trait) instead of falling unconscious, provided that he isn’t inr sunlight. If he can’t transform, he is destroyed.

While he has 0 hit points in mist form, he can’t revert to his avatar form, and he must reach his plane within 2 hours or be destroyed. Once in his plane, he reverts to his avatar form. He is then paralyzed until he regains at least 50 hit points. After 1 hour in his plane with 0 hit points, he regains 50 hit points.

Regeneration. Erberus regains 30 hit points at the start of his turn if he has at least 1 hit point and isn’t in sunlight. If he takes radiant damage , this trait doesn’t function at the start of his next turn.

Warlock abilities.

Devil's sight. You can see normally in darkness, both magical and nonmagical, to a distance of 120 ft.

Relentless Hex. Your curse creates a temporary bond between you and your target. As a bonus action, you can magically teleport up to 30 feet to an unoccupied space you can see within 5 feet of the target cursed by your hex spell or by a warlock feature of yours, such as Hexblade’s Curse or Sign of Ill Omen. To teleport in this way, you must be able to see the cursed target.

Lifedrinker. When you hit a creature with your pact weapon, the creature takes extra necrotic damage equal to your Charisma modifier

Master of Hexes.

  Hexblade’s Curse from a slain creature to another creature. When the creature cursed by your Hexblade’s Curse dies, you can apply the curse to a different creature you can see within 30 feet of you, provided you aren’t incapacitated. When you apply the curse in this way, you don’t regain hit points from the death of the previously cursed creature.  If the target cursed by your Hexblade’s Curse hits you with an attack roll, you can use your reaction to roll a d6. On a 4 or higher, the attack instead misses you, regardless of its roll

Split Mind. Erberus can concentrate on two spells at once.

God accuracy. Whenever you have advantage on an attack roll using Dexterity, Intelligence, Wisdom, or Charisma, you can reroll one of the dice once.

Eldritch smite. Once per turn when you hit a creature with your pact weapon, you can expend a warlock spell slot to deal an extra 1d8 force damage to the target, plus another 1d8 per level of the spell slot, and you can knock the target prone if it is Huge or smaller.

Multiattack (Avatar Form Only). Erberus makes two attacks, only one of which can be a bite attack.

Unarmed Strike (Avatar or Wolf Form Only). Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) slashing damage plus 14 (4d6) necrotic damage. If the target is a creature, Erberus can grapple it (escape DC 18) instead of dealing the slashing damage.

Bite. Melee Weapon Attack: +9 to hit, reach 5 ft., one willing creature, or a creature that is grappled by Strahd, 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 Erberus regains hit points equal to that amount. The reduction lasts until the target finishes a long rest. The target dies if its hit point maximum is reduced to 0. A humanoid slain in this way and then buried in the ground rises the following night as a vampire spawn under Erberus control.

Blackrazer. Melee Weapon Attack: +16 to hit, reach 5 ft., Hit: 20 (2d6 + 13) piercing damage plus 10 (2d10) necrotic damage.

Whenever you use it to reduce a creature to 0 hit points, the sword slays the creature and devours its soul, unless it is a construct or an undead. A creature whose soul has been devoured by Blackrazor can be restored to life only by a wish spell.

When it devours a soul, Blackrazor grants you temporary hit points equal to the slain creature’s hit point maximum. These hit points fade after 24 hours. As long as these temporary hit points last and you keep Blackrazor in hand, you have advantage on attack rolls, saving throws, and ability checks.

If you hit an undead with this weapon, you take 1d10 necrotic damage and the target regains 1d10 hit points. If this necrotic damage reduces you to 0 hit points, Blackrazor devours your soul.

Soul Hunter

While you hold the weapon, you are aware of the presence of Tiny or larger creatures within 60 feet of you that aren’t constructs or undead. You also can’t be charmed or frightened.

Blackrazor can cast the haste spell on you once per day. It decides when to cast the spell and maintains concentration on it so that you don’t have to.

Charm. Erberus targets one humanoid he can see within 30 feet of him. If the target can seeErberus , the target must succeed on a DC 19 Wisdom saving throw against this magic or be charmed. The charmed target regards Erberus as a trusted friend to be heeded and protected. The target isn’t under Erberus's control, but it takes Erberus's requests and actions in the most favorable way and lets Erberus bite it.

Each time Erberus or his 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 Erberus 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). Erberus magically calls 2d4 swarms of bats or swarms of zombie limbs, provided that the sun isn’t up. While outdoors, Erberus can call 3d6 shadow mastiffs instead. The called creatures arrive in 1d4 rounds, acting as allies of Erberus and obeying his spoken commands. The beasts remain for 1 hour, until Erberus dies, or until he dismisses them as a bonus action.

Strahd can take 4 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. Strahd regains spent legendary actions at the start of his turn.

Move. Erberus teleports 60 feet

Unarmed Strike. Erberus makes one unarmed strike.

Cast Spell (Costs 2 Actions). Erberus cast a spell of 2 or lower.
