Thank you bangbang my thoughts are hammers and maxes even against modern armor will do serious damage consider I g a flak vest only protects against peirci g of the bullet there are many cases of broken ribs and deep bruises. Now let a str 10 troll with a warhammer hit you what do you think?

Even a flak vest is going to provide some protection versus a bunt weapon, if merely by providing padding, so I'd give the armor some effectiveness against them, say 50% armor rating.

Or, just give the weapon a larger AP rating.  There's no need to come up with a new mechanic, especially one that will have a ton of variation.

Yo guys do realize that many people that wear ballistic protection also wear trauma plates in conjunction and they're fully effective against blunt weapons.

And while they aren't nearly as good at protecting you against things like knives compared to bullets, Kevlar is still a tough material.

Which is why the old editions stuff like riot gear armor had higher impact armor vs swat ballstic armor

Oh the glory days of I and B ratings. I loved the complicated realism of combat stats.
