When I first found out how vulnerable the neck was and how a well-placed punch could instantly kill roughly 90% of the things you come across in an average adventure, I was let down when I couldn't grab someone and snap their neck through wrestling. Normally, you can only do tearing damage through wrestling, unless you're breaking a joint. However, if you add [JOINT] to the neck in the body part file, you can perform a neck-breaker that behaves exactly like you would expect. Have a look:
Human 1: Has the tide turned? I must press on!
You grab Human 1 by the neck with your left hand!
Human 1 punches You in the lower body with his left hand, bruising the muscle and bruising the pancreas!
You lock Human 1's upper spine with Your left hand!
You bend Human 1's neck with Your left hand and the upper spine collapses!
A ligament in the upper spine has been torn and a tendon has been torn!
The Human 1 falls over.
Human 1 misses You!
You release the grip of Your left hand from The Human 1's neck.
Human 1 misses You!
Human 1: How fleeting life is... Begone fear!
Human 1 misses You!
Human 1 has suffocated.
The victim is still somehow able to move, speak, and even bite after this, but will eventually suffocate as long they aren't a vampire or something with the [NOBREATHE] tag. It's fully functional and requires next to no modification to the raws, but the wording in the wrestling menu and combats reports might need changing if it were going to be made into a standard feature. I can't think of any reason not to include it apart from that it could make combat easier than intended.
"Oh hello bandit *grab-snap*"
"Hello soldiers *grab-snap grab-snap grab-snap*"
"Hidragonbyedragon *grab-snap*"
Edit: Just to specify, you need to add [JOINT] to [BODY:NECK] to make it work. Adding it to [BODY:HUMANOID_NECK] or anything other whole body entry does nothing. Adding [JOINT] to [BODY:THROAT] will work and is
extremely effective, but produces unrealistic results. Happy modding!
