Vampiric dragon

Vampire Dragons are Lesser Dragons and like real Vampires suck their victumes blood. Their voices are so intimidating that it casts their victumes under a spell. Once the victumes see the vampire dragons they normally revive. Unlike vampires though they do not die in the sunlight they just move slower. If these dragons suck an adult dragon and up they turn into a vampire dragon. If younger they turn into a Zombie Dragon.
