Appearance/discussion of Necropolis units.

Guys, a vampire is just someone's essence. For example, a Paladin, if he could shoot sparks and lightning from his rear, that wouldn't mean he rejected (disregarded) another type of weapon. ;) :D
With a sword on the battlefield (and other types of weapons), it's much more convenient; you don't have to jump and bite at the victim's vulnerable spot. If there's even anything to bite. ;)
