Player Characters as Vampires

Source: Monster Manual p. 295, Van Richten’s Guide to Ravenloft p. 236

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, 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, 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.

Humanoids killed by a jiangshi rise as life-hungry corpses and might turn into jiangshi themselves if they feed upon the living.
