Parasite Destroyer Orb

A powerful energetic device, this orb will orbit your aura, waiting for parasites and vampires to try to latch onto you. When they do, the orb will replicate itself and step between them and you so that their tendrils hit it instead. Then the orb releases powerful bursts of energy, 1000 times every second, to fry the parasite before it knows what happened. And, because it replicates itself when it needs to, you will always have enough orbs to handle the attacks.
