Vampires

In ancient stories and mythology, the vampire is the creature described as the most sinful. Its gluttony knew no bounds, killing all without discrimination or discretion, followed by the desecration of whatever remained. Eventually, all vampires were hunted down, either by the Eternals or by the Disciples of Astrasaz before their destruction. The last known vampire was Archikan Vaerek the Ravenous, who terrorized the city of Kisarakdos some 400 years ago before he was subdued and destroyed.

Characteristics
Soul Devouring - As a full-round action, the vampire feeds on the blood of their grappled or helpless victims and consume their strengths, adding to their accumulated strength. Creatures who have their soul devoured are marked with a viscious looking black mark on wherever the vampire fed.

Creatures who suffer against a vampire's feeding must succeed in a Will save equal to 10 plus half its total hit die rounded up plus its Intelligence modifier. Failing this save results in all of the target's ability scores being reduced by 4d6, to a minimum of 5. This effect is not ability damage or drain and can be restored only through Wish or Miracle, becomes a Lesser vampire themselves, vampire who marked them dies. The Empowered Soul - A vampire is able to pick apart its victims' souls and absorb only the strengths it finds, gaining a variety of bonuses based on the number of souls it has consumed. The souls of non-magical beasts are nowhere as potent as those of sapient or magical creatures and thus require three times as many souls in order to increase their strength. However, Lesser vampires find that the consumption of blood to be a severe addiction and must feed on a soul at least once every week or suffer 1d3 damage to a random ability score every 24 hours until they feed.

When a vampire feeds, any ability damage they have are dispelled as they are restored to their full strength and they restore 1d8 health plus an additional number of 1d8 equal to their hit die. True vampires do not suffer from this affliction, although they do dispel any ability damage they have when they feed. The vampire's CR increases by 1 for every 100 souls they feed on.

A vampire gains the following bonuses as he devours more souls and adds to his strength.  Gluttonous Insanity - Lesser Vampires cannot stand the strain of adding more to their soul than what should be there and every time they consume a soul, they have a cumulative 1% chance to go permanently insane with schizophrenia, usually threatening to devour the soul of whatever it sees. True Vampires embrace the strengthening of their soul and are able to handle the eupohoria associated with it, and do not risk the chance of insanity. Thrall - If a creature with an Intelligence score of 4 or higher dies while marked by a vampire's bite, they are raised at the next new moon as a thrall under the control of the vampire. When it is raised, the creatures type is changed to undead. The thrall retains its subtype and physical ability scores along with any special abilities prior to death, but its mental scores are reduced to 1.

A vampire may have control over a number of thralls equal to its hit die. If it exceeds this number, all the newly created thralls fall under the vampire's control, and any excess undead from previous enthrallments become uncontrolled. The vampire is able to choose which of the older thralls are released. Uncontrolled thralls have a insatiable hunger for blood to restore what was taken from it; however, it gains no benefit upon successful consumption.

Creating Lesser Vampires - A vampire may reduce one of its ability score by 1 to turn a thrall into a Lesser vampire by feeding it some of its own strength. This restores the thrall's ability scores to before the creature was fed on, turning its type to Lesser Vampire. If the original vampire dies, any Lesser Vampires it might have created are now free from mental control.
