While most methods of poisoning a target rely on ingestion, or penetration of
the skin by some method such as a dagger, poison mages have found a much
simpler way to go about this. By hitting the target with a short burst of
energy based upon their knowledge of magical poisons, a toxin can be
introduced into the target without outward physical penetration. This spell
generally causes very sharp pain, but no long term effects. Some creatures are
vulnerable enough to toxins that they may experience some vomiting and some
other irritation to their digestive systems.
