Vampire, Vrykolakas

Vrykolakas Ancient (Creature 13), Vrykolakas Master (Creature 10), Vrykolakas Spawn (Creature 6)

Like vampires vrykolakas can infect victims with their twisted form of vampirism, transforming practically any living monster into one of these undead horrors. You can build a new vrykolakas from the ground up using the standard monster creation rules, which were used to create the vrykolakas spawn, vrykolakas master, and vrykolakas ancient, or you can use the guidelines presented under Creating a Vrykolakas to turn an existing creature (even a player character!) into a vrykolakas, adjusting the monster as you see fit.
