ok I had to re read what lead to this revival of this thread,
some peasant bit into an adventurer and sunder armor.
wait the issue was the peasant got into an alligator death roll on your adventurer's arm and broke it?
so it seems less like what these folks were talking about years ago with how their adventurers are too strong and can't spar(due to toady not adding a spar option to adventurer mode and added a scale of acceptable violence rating, even though one could dfhack toggle on sparring for the adventurer.) as their buff out huge muscles and strength will gib a random site fodder inhabitant ...I mean peasant with one punch.
like from that set up it seems like you're the villain in the scenario and someone got to heroically do a cool move on you to save their lives.
like also take into factor Which race the peasant was, like were you fighting a human peasant as a dwarf then the 10,000 size difference might put you into an disadvantage, then we get into Wrestling as biting legit goes into that if they shook your arm to it's breaking point. though it feels like DF is getting to the era where Knights are going out of style with possible means of creating high powered force range weapons that folks can mod into and or the new magical interactions where someone could look at you funny and melt your organs or give you animal organs, or fling you across the map with the power of force.
so here's a visual doodle of what I pictured the pose the peasant did to break that arm.
also after testing in arena yeah it seems wrestling beats armor so it less force attacks bypassing armor, and more wrestling bypassing armor.
the bite attack probably got deflected from the armor but still latched.
