Elemental /Nature Vampires

Elemental Vampires are individuals that feed off the energies found in nature.  Generally these are Earth, Air, Fire and Water, and Life/Spirit.  Some Vampires feed off of storms (fire, water), Wind (air), Plants / Animals (life), the Sun (fire), Ocean, Earth, or anything else they can sense energy in.  The technique is very similar to Ambient Psychic Feeding.  Another method of feeding is through ritual and the raising of a cone of power, but instead of releasing it to the universe, you draw it into yourself to replenish your energy.
