Mistwell said:Usually /= always, nor does "normally" = "always". Given the hide skill does discussing hiding while immobile (and even a bonus for such, if one is invisible, that is above and beyond the bonus for moving and hiding while invisible). And I think it's obvious that you can hide while not moving. That's what ambush is all about. Do people really think ambushes cannot be done in D&D, or that they do not involve the hide skill?
Man you seem to just want to start an argument for old time's sake.

I really believe we are saying the same thing.
I said (and provided the quote) as to "why" it is listed as usually none, not as to what else that entails only the reason it states "usually none". Precisely because hiding "usually" involves movement and so it is not an action of its own because it is part of the movement.
A hide check that is not part of movement is specifically an action of its own as pointed out in the sniping application.
As I also stated out previously:
IMO you can take 10 with a hide check, as per the normal rules for taking 10.
You can not, however, take 20 since that involves "failure" and if you fail a hide check you are spotted and can then no longer attempt to hide without the circumstances changing first. So no matter how it is attempted (well ahead of time as per seting up an ambush) you can not take 20 because of the way the mechanics of taking 20 work. It has nothing to do with a the skill carrying a penalty for failure or not {IMO one of the common misconceptions of why you can't take 20 on a hide check}. It only has to do with the fact that there is 'automatically' considered a "failure" during the take 20 process and that once a hide check is failed you can not attempt it again under the same circumstances.
