Death Raptor

Death Raptors are winged creatures composed of pure Darkness. They supposedly come from the Abyss and are capable of crossing through dimensions. Death Raptors are like vultures, they are often attracted to ritualistic magicks and they attack wounded Supernaturals, feeding on their supernatural powers as if it were carrion.
Death Raptors attack with wings, claws and beaks. They often stay together in flocks, some quite large, and work together to bring down specific targets. They usually wait until night fall, since their shadow bodies blend in perfectly with the night.
