Vampire Addon brings into play several new mobs and items. All three new mob are vampires that are extremely dangerous. They are all hostile to any friendly beings they encountered. But they have a weakness, and it's daylight. So a great recommendation for you - avoid the night and go out during daylight hours only. Vampires are incredibly fast, so you really have little chance to escape from them.
