It would likely only be successful when a larger entity is wrestling a smaller entity, like ogre vs dwarf, or dwarf vs rabbit, and so on.
Did you mean to say ONLY? Hmm. I thought this was to occur whenever it presented itself.
I said "Likely only successful" because you seem to need a pretty good strength advantage to perform joint breaks.
Okay, I'm fine with this example. As long as it doesn't progress into becoming a lethal attack.
Of course breaking something's neck is mostly going to be lethal, if it damages the upper spine enough to cause the lungs to stop working. I guess there'd be the rare instance where it isn't, just like creatures occasionally have their skulls shattered and their brain doesn't get torn.
Why? Well you see I don't want to void existing code. The game tracks victorious kills a weapon earns, for various unknown reasons. I guess for naming, slayer bonuses, artifact making, and engravings. *shrug*
With a wrestling hold doing more than a knockdown, and immobilization, wouldn't that negate the entire line of code, that collects kill data on weapons? If this can be avoided, sure, I'll agree, it sounds like a good suggestion. If it cannot, necklock is a one mode furball.
Wrestling is already possibly lethal, so any "weapon data kill code" is already voided, as you claim. You've never had a dwarf die from getting thrown into something? Not to mention the plethora of creatures without weapons to track kills on to begin with. Just because every single kill isn't performed by a weapon does not void the code that deals with it. And the ogre example above applies equally to adventure mode and fortress mode.
On a jovial note. What about Ogre vs Rabbit? Swallow Whole? HA!
That'd be kind of cool. Especially if a huge creature swallowed a dwarf whole, and he was able to cut his way out. But that's a different discussion.
