Well I thought of something. I can add a permission node that literally subtracts the flat (before armor) damage that they do globally. .5 hearts, 1 heart, probably enough to make a difference. Because its PEX it can even be a timed node. It wouldn't be publicized, and I probably wouldn't even tell the player that it had been done to them, except to say that they have been punished appropriately to match their crime.
