The mod adds two mobs. 1.Werewolf 2.Vampire if you attack a vampire it will turn you into a Vampire. And if you attack a werewolf it will turn you in to a Werewolf. and if you die via Zombie attack you turn in to a zombie. so if ur attacked by a vamp, or wolf, or zombie it will say You Are Now A Vamp or what ever you were attacked by. if you are a vamp you burn in sunlight so does zombie.

Here is a sprout included version. Enjoy! http://forums.bukkit.org/threads/read-first-what-can-plugins-actually-do-using-spout.31688/
