If you want to get rid of them then that is your only option.

You see, if you shield yourself from them, then they will drain your shield that you used your energy for to create in the first place, as if its their appetiser.

But if you drain them, or your shield is draining them, that is like creating a vacuum, they will not be able to drain as much as they wanted and gladly skip you and look for an easier meal. 

As a vampire myself I don't like to be drained, at least not when I don't expect it. I can exchange energy if you ask nicely. Vampires don't only suck energy, they can give off too.

I live near a new age (hippy) camp where a few shamans and spirituality enhanced people live.
All these new agers keep trying to shield themselves and I still am able to feed off them.

They now accepted the fact that not everyone can be cleansed with sage and white light and such. There are some amongst us that bathe in darkness and such for that same purpose.

what kind of ritual or gesture do you do to spawn a vacuum for the energy vampires? Does it move with you?
