Re: Another "would you allow this in your campaign" question...
Actually, there is a physiological effect for tasers. Tasers fire hooks into the skin of the target and deliver 50k volts of electricity, which causes a "short circuit" in the brain, which is what you are describing. There are, however, also muscular contractions effecting the heart and diaghram.
So, for a conventional taser those hooks might have a tough time penetrating armor or resistant defenses.
