Aaah, flat strikes. I flat out forgot about those!
Ok terrible puns aside, it seems I haven't adjusted the flat attacks velocity since the first version at all. I could adjust them to more reasonable values fairly easily, though I suppose its worth considering removing them entirely as the AI can't tell the difference between a lethal secondary attack (like a pommel bash) and a non-lethal secondary attack.
The face parts right now are left as the vanilla ones, which is to say pretty broken. For some reason they are not at all covered by the helmet, hits on them do not translate to damage to the actual head at all, the AI is way to fond of using any 'high roll' attacks they get on them and any clothing that extends two steps from the upper body
does cover them. This is the culprit behind all the weirdness with bruised eyelids and noses getting scratched being blocked only by body clothing. Its not even the weirdest I have seen, my character once decided to bite and rip out someone's tongue, unimpeded by his helmet, face and general logic.
I have no luck in fixing this so far, at all. Making them embedded does nothing beside making them impossible to sever, making them internal causes the hits on the head to smash every single facial feature at once, and somewhere along the line it went and caused that weird invincible head bug. Removing them entirely is also problematic is a whole lot of creature entries reference them for descriptions like long noses and such. Teeth are even more annoying as they are used by attacks so I can't replace those with a dummy bodypart either.
A few historic notes: An aketon is a padded jacket, often with long sleeves. The names are somewhat ambiguous and often interchangeable, but here its the thinner version worn under armor or worn by civilians, often more for fashion than protection. For this mod it also covers the legs as making separate padded breeches once more causes the annoying double armor coverage on the lower body. Its not supposed to cover any part of the head, that's an annoying side effect of making a piece of body clothing/armor that covers the whole arms.
Slapping someone in armor with the flat of a longsword really hard would not break it, they are fairly flexible. Of course this does make a slap like that breaking bones through armor all the more silly.
Anyhow I will either remove the flat attacks or severely weaken them for the next version. For the face bits I'm really not sure what to do though...
