Half Vampire Half Werewolf:

Half Vampire Half Werewolf are called werewolf-vampire half breeds.  There are two ways this could happen.  The first way would be if a werewolf is bitten by a vampire.  This is of course extremely rare – but conceivably this could happen. It does not work in reverse however – if a werewolf bites a vampire you do not get a half-breed.  The second instance in which you’d get a werewolf-vampire half breed would be if a werewolf and vampire have a baby.

This could happen, but it is much much less likely to happen – and I am not aware of any cases.  The problem is that werewolves and vampires do not get along, so it is highly unlikely that they would have children together. The only possible way would be if the werewolf would be able to trick the vampire into it while the werewolf is in human form.  This would not happen though because werewolves and vampires have been at war for eons.

 If one of the two cases above does happen,  what you end up with is a creature that is a werewolf for all practical purposes – lives as human and transforms during the full moon.  This creature however  does not have a soul and it also lives forever.  The half-breed werewolf thirsts for blood only – not just to attack, but to eat, and it comes out only in the nighttime.  The werewolf-vampire half breed is much much more dangerous than a pure werewolf or pure vampire.

Half Werewolf:

The half werewolf is  a being that is half werewolf and half some other type of  creature.  Half werewolves are a pretty rare occurrence, though do exist.  The two most common forms of the half werewolf include the half werewolf – half human and the werepire.

Half-Vampire:

Half-Vampires are known as disasters and mistakes of the human kind. As excommunicated creatures of society, they make their own small communities.

Description About Vampire:

Half-Vampires love heights and are considerably agile.

Half-Vampires typically stand from 5 feet to a little over 6 feet tall and weigh from 125 to 250 pounds with men noticeably taller and heavier than women. Half-Vampires are known as bad makers and even once ordered a constitution of terror in lands.

Half-Vampires are one of the most excommunicated races ever. They have tall (or small) relationships with demons sometimes even finishing in partnership in a descendant.

 Half-Vampires tend towards the evil order alignments. You can find good half-vampires and they can be rarely found working as vampire slayers.

Vampires do not have any lands. If they are also half-human, they blend into the society (of the humans).

Half-Vampires commonly worship Fist, god of plagues and battle. Fist is the symbol of bad for them and they say that he will once be the ruler of all things bad. Half-Vampires worship Fist because it is said that he is a slayed vampire himself

Half-Vampires speak their own language, vamperion. They typically learn other languages, especially abyssal. Half-Vampires have a disgusting language and evil foes love speaking it.

Half-Vampires usually use human or other names (depending on their cross breeding parents) in their society so they can hide their identity. The half-vampire regular names come mostly from abyssal phrases.
Male Names: Barovamor, Govbastar, Madesopweq, Olfcopxz, Xzvap, Cavxz-bengaf, Hoxdrewm, Jalabell, Uzasetr, and Fulpadwer. Female Names: Yuf, Gupbmer, Falbedyem, Tolacng, Holknav, Rumigat, Keletrayam, Opasa, Qualistdxz, Xzx-matxz

Half-Vampires commonly go on adventures to get blood for their friends. The good half-vampires often go on adventures for the purpose of slaying vampires.

* Medium-size: As Medium-size creatures, half-vampires have no special bonuses or penalties due to their size.
* Half-vampire base speed is 40 feet.
* Blood Drain: As vampires, these creatures can drain blood, although this blood drain results just in temporary constitution damage. See page 221 in the monster manual for more information about this special ability.
* Gaseous Form: This ability is similar to the one that the vampires have, although, flying time is reduced to 20 minutes only per day. See page 221 in the monster manual for more information about this special ability.
* Fly: Vampires can fly 2 hours a day in their base speed unless having an armor that reduces the speed.
