Actually, I was messing around with PDCs and came up with the greatest pacifist PDC. Wormhole PDCs

They work excellent against fighters and seekers, and no harm is ever done to the people

But if you wanted to make your own, just change the damage type on the existing (or copy them)to either 'skips armor' or something similar.
FYI: damage types are listed at the top of the components file.
