I would like to note that basic logic states that just because set A is not a subset of set B doesn't mean set B isn't a subset of set A. As well, just because it separates them by name implicitly doesn't mean they are explicitly separate. While I haven't seen conclusive proof that Unarmed Strikes are Natural Weapons, I haven't seen anything I'd treat as conclusive evidence that they aren't since there is evidence they COULD be.
There is no evidence they *could* be.
* US rules are found in Weapons and does not say it's a NW.
Thread over.* NWs, of course, have their own separate entry and does not contain US.
Thread twice over, suggestions otherwise are already homebrew.* Combat treats Weapons, US, and NWs separate. However, Weapons and US use the same Attack Arrangement,
NWs don't. Homebrew in this area is not a "fix" of missing terms, but a "clusterfuck". If you treated US as a NW in your game, doesn't that mean I cannot make a second attack, ever? And under your rule set, are treated as primary or secondary weapons? If you ruled I gain additional attacks with my NW for higher BAB, then I could full-attack with a sai and then 'full-attack' with my NWs due to the ability to combine the two as part of a (real) Full-Attack. More and more f'ing houserules have to be added every time your Player wants to use the stupid idea all because you made one hell of a horrible call.* The FAQ contains several entries stating you cannot use Natural Weapons with Furry of Blows.
Even goes as far as flat out telling you US is not a NW. The FAQ is literately the highest priority of the game, it was a continually updated rules addition that answers extremely specific questions and is based on the interpretation clarification and rules delegation. The FAQ wants to say US isn't a NW it can. And guess what, there isn't even relevant text arguing otherwise.* Rules of the Game also flat out says US is not a NW.
Skip Williams, Monte Cook, and Jonathan Tweet were the PHB 3.5 design team. Skip Williams in turn has an officially published article on WotC's site under the article line dubbed the f'ing Rules Of The Game that tells you you're wrong and see that combat section as proof otherwise.Ergo, we've got two official sources telling me you just failed at reading and you need to stop deliberately being thick-headed and argumentative. US/NW is silent on the issue but the FAQ, RotG, and the PHB/RC combat section all say US is not a NW, the latter technically doesn't outright state such which is why WotC thought they
needed to address the issue and that's why the FAQ exists in the first place. ~Silly people like you can read one thing and pretend it's something else entirely. All points have been covered, multiple times, and I refuse to partake in this freak show where you should be how far you can shove your head up your ass. So as you in turn discuss how you don't like D&D's rules and about your house rules are better, you'd better be talking to those voices in your head because I'm sure the hell not listening to it.
